Magnetic interaction in the manganite/intermetallic compound heterostructure

We investigate hybrid magnetic heterostructures consisting of thin epitaxial films of oxide ferromagnets La0.7Sr0.3MnO3 and intermetallic superlattices (TeCo2/FeCo) n . The magnetic characteristics of the heterostructures were studied by the ferromagnetic resonance and magneto-optical Kerr effect techniques. The interlayer interaction in a heterostructure is shown to be antiferromagnetic. It was established that the interface with the intermetallic compound broadens the ferromagnetic resonance line of the manganite film.
