“…1 The process of magnetization reversal, sensitive to phase composition, microstructure, etc., [2][3][4] has been investigated extensively to improve the magnetic properties. [5][6][7][8][9][10][11][12][13][14][15][16] Using different analysis methods or different types of samples, the process of magnetization reversal will change from conventional domain nucleation, 12,13 domain wall pinning, [5][6][7] to self-pinning at soft/hard interface. 14 It seems difficult to find intrinsic properties in the process of magnetization reversal.…”

The magnetization behaviors show a strong pinning effect on domain wall motion in optimally melt-spun Pr8Fe87B5 ribbons at room temperature. According to analysis, the coercivity is determined by the nucleation field of reversed domain, and the pinning effect, which results from the weak exchange coupling at interface, makes domain nucleation processes independent and leads to non-uniform magnetization reversals. At a temperature of 60 K, owing to the weak exchange coupling between soft-hard grains, magnetization reversal undergoes processes of spring domain nucleation in soft grains and irreversible domain nucleation in hard grains, and the pinning effect remains strong among hard grains.

“…In recent years, nanocomposite magnets have attracted considerable attention due to their high remanence ratio, great energy product and low rare-earth content [1][2][3]. The high performance is attributed to the intergrain exchange interactions between the hard-magnetic grains and the soft-magnetic grains.…”
