摘要：
Hetero-amorphous (Fe0.75Co0.25)(1-x)(B1-yCy)(x) films have been obtained by RF magnetron sputtering. Magnetic properties strongly depended on the heteroamorphous substructure of the films. The film with a fine substructure less than 10 nm in mean diameter exhibited low coercive force of 40 A/m along the hard axis, large spontaneous magnetization of 1.6 T, and in-plane anisotropy field of 1.2 kA/m induced by field-annealing although the film had a large magnetostriction constant of 39x10(-6).
