dc.description.abstractThe mechanism for ion-induced uniaxial magnetic anisotropy of ferromagnetic CoPt thin films is investigated using x-ray diffraction and soft x-ray emission spectroscopy. When Co/Pt multilayers 64 nm thick are irradiated with 80 keV Ar+ ions in an externally applied magnetic field, the magnetization of the ion-irradiated area shows a significant anisotropic angular dispersion in its hysteresis. Analysis of x-ray diffraction patterns and Co L-3 emission spectra reveals that the formation of partially ordered (face-centered-tetragonal) CoPt phase and nonequivalent electronic hybridization between easy and hard axes causes the induction of a uniaxial magnetic anisotropy.-
