Нybrid magnetic heterostructures consisting of thin epitaxial ferromagnetic manganite film La0.7Sr0.3MnO3 and superlattices of intermetallic compound (TeCo2 / FeCo)n are stadied. Using the magneto-optical Kerr effect and vibration magnetometer we studied magnetic properties of heterostructures. It is shown that the features observed on the curves of the magnetoresistance in heterostructure, is associated with the interaction of the magnetic layers in the structure.
