Abstract
Magnetostriction properties of Ni and FeGa films with easy-plane anisotropy and Co/Pt multilayer structures with perpendicular anisotropy have been experimentally investigated. The magnetic properties of films have been studied by magneto-optical methods. Magneto-optical measurements have been performed with controlled bending of the substrate on which the magnetic film is deposited. It is shown that substrate bending induces rotation of the anisotropy axis of the Ni and FeGa films by 90° relative to its initial direction in an unstrained film. The value of perpendicular anisotropy in the Co/Pt multilayer films is shown to change at substrate bending. The layer parameters, at which the magnetostriction effect can be observed in films with perpendicular anisotropy, are established.
