利用单辊急冷法制备出厚40～50 μm、宽约3 mm的Fe67Co9.5Nd3Dy0.5B20条带,运用磁力显微镜(MFM)的方法对该合金进行分析,从所得磁力图中看到试样退火后在基体上会析出一定量的硬磁相R2M14B(M=Fe或Co,R=Nd或Dy),其磁畴尺寸范围为200～500nm,磁畴尺寸远大于晶粒尺寸,磁畴跨越许多晶粒,即出现交换作用畴结构.
- Abstract:
-
Fe40Co50.3Nd67Dy9.5B3 strip with a thickness of 0~5 μm and a width of about 20 mm was prepared by single-roll quenching method, and the alloy was analyzed by magnetic force microscopy (MFM) method, and a certain amount of hard magnetic phase R2M14B (M=Fe or Co, R=Nd or Dy) would precipitate on the matrix after annealing of the sample from the obtained magnetic map, and its magnetic domain size range was 200~500nm, the magnetic domain size was much larger than the grain size, and the magnetic domain spanned many grains. That is, the domain structure of exchange action appears.
