Abstract

We report on the investigations of the magnetic properties and ferromagnetic resonance in the heterostructure consisting of an epitaxial yttrium iron garnet (Y3Fe5O12) film and a nanometer rare-earth intermetallic superlattice comprised of the (TbCo2/FeCo)n exchange-coupled layers. The (TbCo2/FeCo)n superlattice exhibits the giant magnetostriction and the controlled magnetic anisotropy induced by a magnetic field or elastic stresses. The magnetic interaction of the films in the (TbCo2/FeCo)n/Y3Fe5O12 heterostructure has been experimentally established and the spin current flowing through their interface has been detected.
