DEPENDENCE OF STRUCTURAL AND MAGNETIC PROPERTIES ON DEPOSITTION ANGLE IN EVAPORATED Co/Pt MULTILAYER THIN FILMS

Abstract

We have investigated the effects of deposition angle on structural and magnetic properties of e-beam evaporated (4-Å Co/9.2-Å Pt)_23 multilayer thin films prepared on tilted substrates. It was found that the [111] crystallographic orientations of the multilayer thin films were not aligned with colummar growth orientations and they were remained to be normal to the substrate planes even though the deposition angle was severely oblique up to 60˚. The analysis of the torque curve reveal that the intrinsic anisotropy energy was monotonically decreased with the deposition angle but the easy axis orientation parallel to the substrate normal was not much influenced by deposition angle.
