【 摘 要 】

Fe36Co36B19.2Si4.8Nb4 BMG rods with diameter of 3mm and amorphous ribbons with thickness of 100μm were prepared with methods of copper mold suction casting and melt-spinning, respectively. These metallic glasses were annealed at different temperatures in vacuum, and the changes of structures and magnetic properties were analyzed. The hysteresis loops were tested by B-H loop tracer and the magnetic domain structures were characterized with MFM. Results show that annealing between Tg and Tx leads to the best soft magnetic property, and this is referred to be induced by the migration of magnetic domain walls.
