Abstract:The magnetic properties of Co/Pt multilayers grown by ion beam and DC magnetron sputtering techniques are compared. For Pt/Co/Pt films the spin reorientation as a function of Co thickness is investigated in second-order uniaxial anisotropy approximation. The influence of the growth technique on the interface and volume contribution to the first-order anisotropy is investigated. The correlations between structure and magnetic properties are discussed.
