摘要
Amorphous wires and ribbons of composition Co70.5Fe4.5Si15B10 have a very small magnetostriction and very low coercivities for wall motion. Their high permeabilities are of considerable technological interest [1]. Thin films of these alloys might be useful for applications, but had not been previously studied. This work studied the structural and magnetic properties amorphous thin films sputtered from an alloy target with the composition Co70.5Fe4.5Si15B10. The results obtained show, that the coercivity and in-plane anisotropy of the sputtered films are much larger than those of ribbons and wires. Attempts to reduce these parameters by varying the processing and annealing parameters, substrate material, composition, and film thickness were largely unsuccessful. While these results are not understood, the composite data suggests that the higher values may be due to micro-compositional inhomogeneities quench rates of sputtering.
