Abstract
Thin Co62.5Ni30Cr7.5 films were rf-sputtered onto glass and Cr/glass. Magnetic anisotropy, coercivity and magnetization were compared with inferences from structural characterization. For CoNiCr/glass narrow FMR line widths ƊH, low coercivity Hc and effective anisotropy field Hkeff values close to 4πMs were observed. For CoNiCr/Cr/glass broader ƊH, larger Hc and Hkeff deviating from 4πMs were observed. Crystal texture and grain growth depended on the presence/absence of a Cr underlayer.
