- 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.
