Abstract

Thermally-controlled exchange coupling between two strong ferromagnetic (FM) layers separated by a weak FM spacer has promising application in current-driven spintronic devices. In this thesis magnetic property of Ni xFe1-x thin films in the Invar composition range are studied. The focus is on investigating the magnetic transition from ferromagnetic to paramagnetic state of the material and finding the composition with lowest Curie point.

The fabrication process of NixFe1-x  thin films having variable Ni concentration using multi magnetron sputtering is described in the first part of the thesis. In the second part of the thesis the magnetic characterization technique and measurement results are discussed. The Invar effect is observed at approximately 30% Ni content, where the films exhibit a pronounced minimum in the Curie temperature versus Ni concentration
