Abstract

Hybrid magnetic heterostructures made of epitaxial manganite La_0.7Sr_0.3MnO₃ thin film and intermetallic superlattice (TeCo₂/FeCo)_n were prepared on orthorhombic NdGaO₃ substrates and characterized by means of magneto-optical Kerr effect and magnetoresistance. Experimental data show that magnetic interaction between La_0.7Sr_0.3MnO₃ and (TeCo₂ /FeCo)_n is of the antiferromagnetic type. The features observed in magnetotransport characteristics are caused by the magnetization reversal at the interface between manganite thin film and intermetallic superlattice.
