Glassy Fe77Ga3P9.5C4B4Si2.5 alloy powders were synthesized in the particle size range below 125 µm by Ar gas atomization. A glassy alloy disc of 10 mm in diameter and 3 mm in thickness with a high relative density of 99.7 % was synthesized by spark plasma sintering. The resulting glassy magnetic core exhibits good soft magnetic properties, i.e., 1.35 T for saturation magnetization, 5 A/m for coercive force and 9600 for maximum permeability.
