| 5 | Metamagnetic transitions and anomalous magnetoresistance in EuAg4As2 crystals显示文摘In this work,we systematically studied the magnetic and transport properties of EuAg4As2 single crystals.It was found that the two antiferromagnetic transitions(TN1=10 K and TN2=15 K)were driven to lower temperatures by an applied magnetic field.Below TN1,two successive metamagnetic transitions were observed when a magnetic field was applied in the ab plane(H//abplane).For both H//ab and H//c,EuAg4As2 showed a positive,unexpectedly large magnetoresistance(up to 202%)in lower magnetic fields below TN1,and a large negative magnetoresistance(up to-78%)at high fields/intermediate temperatures,thus presenting potential applications in magnetic sensors.Finally,the magnetic phase diagrams of EuAg4As2 were constructed for both H//ab and H//c using the resistivity and magnetisation data. | QinQing Zhu Liang Li ZhiHua Yang ZheFeng Lou JianHua Du JinHu Yang Bin Chen HangDong Wang MingHu Fang | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，2： | 0 |
| 6 | Comparative Analysis of a Rare Autumn Rainstorm and a Spring Rainstorm in Xiamen Area显示文摘According to Ouyang potential temperature V-3θ charts,a rare autumn rainstorm in Xiamen on November 18,2011 was compared with a spring rainstorm on March 29,2005 firstly,and then the main characteristics of the autumn rainstorm were analyzed based on wind profiler data of Doppler weather radar. The results showed that ultra-low temperature on the top of the troposphere was more obvious in autumn than that in spring;clockwise tumble effect was distinct and warm and wet layer reached 300 hPa in both spring and autumn. Clockwise tumble effect appeared in various forms in autumn and spring. That is,the wind blew from the east at low altitudes and the west at high altitudes before the autumn rainstorm occurred; when the maximum wind speed appeared at 500 hPa,heavy rainfall occurred. During the spring rainstorm process,wind direction was consistent at each level and wind speed increased with the rise of altitude during early days. Afterwards,the wind blew from the east at low altitudes and the west at high altitudes. During the autumn rainstorm process,the heavy rainfall at the first stage was closely related to thickness of the 20m /s wind speed layer at 3-5 km. If the thickness declined sharply when the 20 m /s wind speed layer expended downwards,heavy rainfall would occur soon afterwards. Moreover,the precipitation intensity weakened immediately as the 20 m /s wind speed layer began to be stable. The heavy rainfall at the second stage was closely related to thickness of the 24 m /s wind speed layer,and the appearance,development and weakening of the 24 m /s wind speed layer foreboded the occurrence of heavy rainfall. Moreover,the thickness of the 24 m /s wind speed layer decreased to the minimum,and then heavy rainfall would appear soon afterwards. Hereafter,the thickness increased and then decreased again. | Luo Zhonghong Jiang Hangdong Shen Huaping Chen Yiliang | 2014 | Meteorological and Environmental Research2014，5，2： | 0 |
| 7 | Large unsaturated positive and negative magnetoresistance in Weyl semimetal TaP显示文摘After successfully growing single-crystal Ta P, we measured its longitudinal resistivity(ρxx) and Hall resistivity(ρyx) at magnetic fields up to 9 T in the temperature range of 2-300 K. At 8 T, the magnetoresistance(MR) reached 3.28 × 105% at 2 K, 176%at 300 K. Neither value appeared saturated. We confirmed that Ta P is a hole-electron compensated semimetal with a low carrier concentration and high hole mobility of μh=3.71 × 10~5cm^2/V s, and found that a magnetic-field-induced metal-insulator transition occurs at room temperature. Remarkably, because a magnetic field(H) was applied in parallel to the electric field(E), a negative MR due to a chiral anomaly was observed and reached-3000% at 9 T without any sign of saturation, either, which is in contrast to other Weyl semimetals(WSMs). The analysis of the Shubnikov-de Haas(Sd H) oscillations superimposed on the MR revealed that a nontrivial Berry's phase with a strong offset of 0.3958, which is the characteristic feature of charge carriers enclosing a Weyl node. These results indicate that Ta P is a promising candidate not only for revealing fundamental physics of the WSM state but also for some novel applications. | JianHua Du HangDong Wang Qin Chen OianHui Mao Rajwali Khan BinJie XU YuXing Zhou YanNan Zhang JinHu Yang Bin Chen ChunMu Feng MingHu Fang | 2016 | Science China(Physics,Mechanics & Astronomy)2016，59，5： | 0 |
| 8 | Bulk superconductivity in the Dirac semimetal TlSb显示文摘A feasible strategy for realizing the Majorana fermions is searching for a simple compound with both bulk superconductivity and Dirac surface states.In this paper,we perform calculations of electronic band structure,the Fermi surface,and the surface states,and measure the resistivity,magnetization,and specific heat of a TlSb compound with a CsCl-type structure.The band structure calculations show that TlSb is a Dirac semimetal when spin-orbit coupling is considered.TlSb is first determined to be a type-Ⅱsuperconductor with T_(c)=4.38 K,Hc1(0)=148 Oe,H_(c2)(0)=1.12 T,andκ_(GL)=10.6.We also confirm that TlSb is a moderately coupled s-wave superconductor.Although we cannot determine the band near the Fermi level EF that is responsible for superconductivity,its coexistence with topological surface states implies that the TlSb compound may be a simple material platform to realize the fault-tolerant quantum computations. | YuXing Zhou Bin Li ZheFeng Lou HuanCheng Chen Qin Chen BinJie Xu ChunXiang Wu JianHua Du JinHu Yang HangDong Wang MingHu Fang | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，4： | 0 |
| 9 | Visible light induced the high-efficiency spirocyclization reaction of propynamide and thiophenols via recyclable catalyst Pd/ZrO2显示文摘A new method for the synthesis of 3-thioazaspiro[4,5]trienones was developed using Pd nanoparticle catalysts,which are highly efficient,environmentally friendly and recyclable.Alkynes and thiophene phenols are effectively cyclized by Pd/ZrO2 catalyst under visible light irradiation.The present protocol simply utilizes visible light as the safe and ecofriendly energy source,and the Pd/ZrO2 nanocomposite as photocatalyst provides a simple and practical approach to various 3-thioazaspiro[4,5]trienones in moderate conditions to high yields. | Nannan Zhang Hangdong Zuo Chen Xu Junyi Pan Jun Sun Cheng Guo | 2020 | Chinese Chemical Letters2020，31，2： | 0 |
| 10 | Study on Temporal-spatial Change Characteristics of the Extremely Low Temperature Climate Event in Winter of China显示文摘[Objective] The research aimed to study temporal-spatial change characteristics of the extremely low temperature climate event in winter of China. [Method] By using actual probability distribution threshold value method, EOF analysis method and the daily minimum temperature data in winter of 1961-2008 at 195 observatories of China, temporal-spatial change characteristics of the extremely low temperature climate event in winter of China in 48 years were analyzed. [Result] Threshold value calculated by actual probability distribution was higher than that by traditional method, and increase magnitude in east was bigger than that in west, which could describe climatic change situation in China in 48 years better than traditional method. Cold night number in winter of China did not decrease as latitude declined, and it was more in south and north and was less in Yellow River basin and northwest China. Cold night number was the most in northeast Inner Mongolia. Interannual change of the cold night number presented decline tendency. From the 1960s to the early 1970s, cold night number consistently increased, and change in middle and late periods of the 1960s was severe. From the early 1970s to the middle 1980s, fluctuation of the cold night number was bigger, and increase of the cold night number was the most in 1976. Cold night number from 1986 to the 21st century continuously declined. Change of the cold night number was the most obvious in east region, Guizhou and north Guangxi. Cold night number in northeast China and north Inner Mongolia presented inverting change relationship with that in Yunnan-Kweichow Plateau and Hexi Corridor. [Conclusion] The research provided reference for early warning of the extremely low temperature event in China. | Zhonghong Luo Hangdong Jiang Jiangyong Pan Jiayou Huang | 2013 | Meteorological and Environmental Research2013，4，4： | 0 |
