Microstructural and magnetic properties of metallic thin films obliquely sputtered on polymer

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