Abstract. The magnetic properties of the heterostructures consisting of platinum Pt, epitaxially grown manganite optimally doped by strontium La0.7Sr0.3MnO3 (LSMO), rare earth intermetallic superlattices consisting of exchange-coupled layers TbCo2/FeCo (TCFC), and the epitaxial film of yttrium iron garnet Y3Fe5O12 (YIG) were investigated. The TCFC material provides giant magnetostriction, large magnitude of the magnetomechanical coupling coefficient, and controlled induced magnetic anisotropy. In addition TCFC, as well as Pt, has strong spin-orbit interaction. Experimental studies have shown that the magnetic interaction of the heterostructure (TeCo2/FeCo)n/LSMO has an antiferromagnetic character. An increase of linewidth of the ferromagnetic resonance in the Pt/LSMO structure was observed and explained by the spin current flow induced in Pt film by the LSMO film at ferromagnetic resonance. In the TCFC/YIG heterostructure, an electric voltage induced in the TCFC film was observed and explained by the inverse spin-Hall effect under conditions of ferromagnetic resonance.
