Pulse current training induced marked improvement of soft magnetic properties in Fe-based amorphous alloys
It is difficult to fine-tune the atomic local structure and magnetic domain structure globally to evade the saturation magnetization (Bs)- coercivity (Hc) trade-off in amorphous alloys with high-Fe content. Herein, a unique pulse current training is introduced to optimize the soft magnetic propertie...

| description | It is difficult to fine-tune the atomic local structure and magnetic domain structure globally to evade the saturation magnetization (Bs)- coercivity (Hc) trade-off in amorphous alloys with high-Fe content. Herein, a unique pulse current training is introduced to optimize the soft magnetic properties of Fe-based amorphous alloys, achieving 1.78 T Bs and 1.6 A/m Hc in Fe83.3Si4B8P4Cu0.7. Structural analysis shows that low coercivity is due to the almost no pinning-sites magnetic domain structures despite a relative large grain size of 25 nm. Training accumulates energy to activate soft regions and rearrange structure, eliminating quenching-induced stresses and inhomogeneities to minimize reversal pinning. |
