Structure and soft magnetic properties were investigated for a bulk glassy Fe{sub 70}Al{sub 5}Ga{sub 2}P{sub 10.05}B{sub 4.6}Si{sub 2.6} alloy in a ring shape form with an outer diameter of 10 mm, an inner diameter of 6 mm and a thickness of 1 mm prepared by copper mold casting. The bulk sample consisted of only a single amorphous phase. The supercooled liquid region, saturation magnetization, and Curie temperature for the bulk sample are about 60 K, 1.2 T, and 620 K, respectively, in agreement with that of the corresponding amorphous alloy ribbon. The maximum permeability and the coercivity for the bulk sample are about 110,000 and 2.2 A/m. These good soft magnetic properties of the bulk glassy alloy are presumably due to a higher degree of structural homogeneity resulting from its high glass-forming-ability. Therefore, these excellent soft magnetic properties as well as the very high castability for the Fe-Al-Ga-P-C-B-Si glassy alloy allows us to expect that this glassy alloy will be used as one of engineering magnetic materials.
