The paper aims to develop an excellent soft magnetic glassy alloy with a series of (Fe_(1-x)Ni_x)_(79)P_5B_(12)Si_3C_1 (x = 0, 0.2, 0.4, 0.5, 0.6). The annealing at (T_g-20) K for the 0.4Ni-0.5Ni alloys causes an extremely low coercivity below 1 A/m with very high effective permeability above 5-10~4 at 1 kHz in the maintenance of high saturation magnetic flux density of ≌ 1.2 T. Good effective permeability characteristics were recognized as is evidenced from high μ_e values above 6000 at 1 MHz. The core losses at induction of 100 mTare as low as 43 W/kg for 100 kHz and 1150 W/kg at 1 MHz for the annealed 0.6Ni alloy. Excellent soft magnetic properties are presumably due to the achievement of the fully relaxed glassy state which can be obtained only for the glass-type alloys with SCL region. This complex of magnetic properties is promising for future use as high-frequency type soft magnetic materials.
