- Аннотация: An epitaxial heterostructure based on strontium and lanthanum-strontium manganite films (SrMnO3 and La0.7Sr0.3MnO3) is studied. Ferromagnetic resonance spectra, angular dependences of the resonance field for different temperatures, in-plane and cubic anisotropy as well as the temperature dependences of the magnetization, were measured. The obtained magnetic parameters of the heterostructure were compared with the magnetic parameters of a single La0.7Sr0.3MnO3 film. We assume that the existence of an interlayer exchange at the ferromagnet-antiferromagnet interface at low temperatures leads to the appearance of unidirectional anisotropy in the heterostructure SrMnO3/La0.7Sr0.3MnO3. We believe that the presented results will be useful for the practical development of antiferromagnet-based ultrafast devices: emitters, amplifiers, detectors.
