Abstract
The effects of longitudinal magnetic field annealing on soft-magnetic properties (SMPs) and magnetic domain structure of Fe(82.6-85.7)Si(2-4.9)B(9.2-11.2)P(1.5-2.7)C0.8 amorphous alloys with a distinctly high Fe content of 93.5-95.5â¯wt% for high Bs were investigated. It was found that longitudinal magnetic field annealing could improve soft-magnetic properties (SMPs) of amorphous alloys effectively, except the one with poor thermal stability. Superb magnetic properties containing a minimum coercivity of 0.8â¯A/m, a maximum effective permeability of 11â¯Ãâ¯103 at 1â¯kHz and minimum core loss of 0.052â¯W/kg (at Bmâ¯=â¯0.9â¯T and fâ¯=â¯50â¯Hz) were successfully obtained. Domain structures were characterized with a Magneto-optical Kerr Microscope to unveil the mechanism of SMPs improvement. Stripe domains were observed in the annealed high Fe content amorphous alloy ribbons with optimal soft magnetic properties.
