| Abstract(in English) | The origin of high anisotropy field H_k and low coercivity H_k of Fe-Co-B/Ni-Fe double layered film with high 4πM_s was investigated. In-plane and out-of-plane XRD studies clarified that the lattice spacing of planes along the easy axis direction was expanded than that along the hard axis direction. The fact was confirmed that such stress caused by the lattice expansion had significant effects on the magnetoelastic energy in this double layer. We investigated the dependence of H_k on Ar gas pressure. It was considered that the anisotropic stress is generated for the deviation of incident angle of sputtered particles. In order to align the magnetic anisotropy field to the cross track direction on a disk, the deposition of the SUL were performed on a rotating disk substrate. We succeeded in production of disk, which has Hk of 280 Oe in a radial direction of the disk in the whole ares of it. |
