Abstract

Structural, magnetic and magnetostrictive behavior of Fe-Co thin films grown on Si <100> substrates has been investigated. Structural studies indicated that the films are polycrystalline in nature with body centered cubic type structure. Magnetostriction was found to decrease with increase in film thicknesses. Magnetization studies exhibited predominant in-plane magnetic anisotropy for all the films. In addition to this, films grown with higher thicknesses also showed presence of out-of-plane magnetic anisotropy co-existing with in-plane magnetic components. This observation was further validated through magnetic microscopy studies. Presence of competing anisotropies has been found to be the reason for the decrease in the magnetostriction with change in film thicknesses.
