FeNi ¯lms were prepared by oblique deposition onto glass substrate using magnetron sputtering deposition technique. The deposition was carried out on a rotating or nonrotating substrate with or without a constant magnetic ¯eld applied parallel to the substrate plane. The magnetic properties of the samples were measured by a magneto-optical Kerr e®ect at room temperature. All ¯lms had in-plane uniaxial magnetic anisotropy. The presence of in-plane magnetic anisotropy was also con¯rmed by the features of the domain structure. The main factor determining the orientation of the induced anisotropy axis of ¯lms was the magnetic ¯eld applied during deposition. © World Scienti¯c Publishing Company.
