Magnetic properties of amorphous Fe-Si thin films

Abstract
Magnetic properties of Fe1−xSix sputtered films were investigated in the range 0⩽x⩽0.43. The films were found to be amorphous for the compositions x⩾0.20. The magnetic moment change upon crystallization depends on x. The magnetostriction seems to be a predominant factor in determing the hysteresis loops. The films in the amorphous state are magnetically soft. An in‐plane uniaxial anisotropy was observed. The direction of the easy axis depends upon x.
