1HIGH-TEMPERATURE AC MAGNETIC PROPERTIES OF NANOCRYSTALLINE FINEMET ALLOYS WITH Co ADDITION显示文摘高温度的交流磁性为(Fe0.5Co0.5 ) 73.5Cu1Nb3 Si13.5B9 合金在各种各样的温度退火了用一个阻抗分析器被调查了。退火的温度 Ta 在合金的高温度的交流磁性上有明显的效果。Hopkinson 山峰仅仅在非结晶的合金出现什么时候 Ta ≤ 703K。作为在 733K 上面的 Ta 增加,复杂起始的渗透β i 的真实部分“逐渐地下降,β i ”在高温度范围与温度更慢慢地减少。高温度(大约 750K ) 为合金的交流起始的渗透在 Ta=763K 退火了被发现了维持 950 的稳定的高价值直到 1 × 105Hz 的频率。为在 Fe73.5Cu1Nb3Si13.5B9 合金的 Fe 的公司的部分替换导致增加在无定形相的居里温度的 110K 附近,比包含 Ge Finemet 高得多合金。Y.H.

2Influence of Co Content on Raman and Photoluminescence Spectra of Co Doped ZnO Nanowires显示文摘Co doped ZnO nanowires with different Co contents have been fabricated by a chemical vapor deposition method. X-ray diffraction results show that all the samples are of single phase and crystallize in wurtzite ZnO structure. The lattice parameter a increases with increasing Co content, while the parameter c has no obvious change with increasing Co. Raman spectra show that the nonpolar E2(High) mode becomes broad and weak with the doping of Co, which indicates that the incorporation of Co causes structural disorder in the crystalline columnar ZnO lattice. The photoluminescence spectra exhibit that the position of the ultraviolet emission shifts to short wavelength and the intensity decreases with increasing Co. The green emission is affected by two contrary factors. It is increased by the introduced defects, but suppressed by the interaction between Co doping and native defects and the later affects it more significantly.Y.Q. Chang P.W. Wang S.L. Ni Y. Long X.D.

4Synthesis and Room Temperature Ferromagnetism of Flower-shaped Mn Doped ZnO Nanostructures显示文摘Large-scale flower-shaped Mn doped ZnO nanostructures have been grown on silicon substrates by simple thermal evaporation at atmospheric pressure.The flower-shaped nanostructure makes up of many nanorods,which are rooted in one center.Analysis of X-ray diffraction,high-resolution transmission electron microscopy and Raman spectra results reveal that the products are of single phase with wurtzite structure.Elemental mapping results show that no impurity clusters exist in the doped materials.The photoluminescence spectra demonstrate that many oxygen vacancies exist in the doped materials,and the crystal quality is improved and the content of oxygen vacancies is decreased by annealing treatment.The flower-shaped Mn doped ZnO nanostructures exhibit ferromagnetic ordering above room temperature,and its magnetization is decreased by the annealing treatment,which indicates that the magnetic behavior of the doped materials may be related to the interaction between Mn doping and the oxygen vacancies.Y.Q.
