Muhammad Irfan等人研究了退火温度对直径为80nm的电沉积Fe_3Ga纳米丝结晶结构相变化、有效各向异性能及磁化影响。采用扫描电镜EDX谱线测定Fe_3Ga纳米丝元素分布,清晰地显示出Fe和Ga的均匀分布,纳米丝间整齐排列,几何形状比值很高,纳米丝晶体结构同烧结温度关系极大。X-射线衍射表明,合成态Fe_3Ga纳米丝呈现明显A2无序相,由DO_3和LI_2析出物组成。随退火温度升高,明显无序相A2或短程有序相DO_3显著减少,晶粒沿稳定LI2相织构化排列,有少量DO_3相析出物。退火热处理
Muhammad Irfan et al. Studied the effect of annealing temperature on the phase structure, effective anisotropy and magnetization of the crystal structure of electrodeposited Fe_3Ga nanowires with a diameter of 80 nm. The elemental distribution of Fe 3 Ga nanowires was confirmed by scanning electron microscopy (EDX). The distribution of Fe 3 Ga nanowires clearly shows the uniform distribution of Fe and Ga. The arrangement of nanowires is neat and the geometry ratio is very high. The structure of nanowires has a great relationship with the sintering temperature. X-ray diffraction shows that the synthesized Fe 3 Ga nanowires exhibit obvious A2 disordered phases and consist of DO 3 and LI 2 precipitates. With the increase of annealing temperature, the apparent disordered phase A2 or short-order ordered phase DO_3 significantly decreased, and the grains were arranged along the stable LI2 phase with a small amount of DO_3 phase precipitates.
