Abstract
Co and Co–Ni films have been obliquely sputtered on polymer substrate. Depending on the incidence angle, a large in-plane magnetic anisotropy can be induced. The origin of magnetic anisotropy is mainly related to the columnar structure because of the low magnetocrystalline anisotropy in the films (FCC Co). The rotational hysteresis analysis suggests that the magnetization reverse by incoherent rotation in films with a large in-plane anisotropy.
