Abstract
Hybrid magnetic heterostructures made of epitaxial manganite La0.7Sr0.3 MnO3 thin film and an intermetallic superlattice (TeCo2/FeCo) n were prepared on orthorhombic NdGaO3 substrates and characterized by means of magneto-optical Kerr effect, magnetoresistance and ferromagnetic resonance. Experimental data show that magnetic interaction between La0.7Sr0.3MnO3 and (TeCo2/FeCo) n is of an antiferromagnetic nature. The features observed in magnetotransport characteristics are caused by the magnetization reversal at the interface between manganite thin film and intermetallic superlattice.
