【 摘 要 】

Epitaxial La0.7Sr0.3MnO3/BiFeO3 and La0.7Sr0.3MnO3/PbZr20Ti80O3 heterostructures were grown on SrTiO3 substrates via pulsed laser deposition. We employed spin wave resonances to study the interfacial properties of the ferromagnetic La0.7Sr0.3MnO3 thin film. We found that the addition of the BiFeO3 or PbZr20Ti80O3 ferroelectric capping layers may cause out-of-plane surface pinning of La0.7Sr0.3MnO3. We are able to place limits on the exchange constant D of La0.7Sr0.3MnO3 grown on these substrates and confirm the presence of uniaxial and biaxial anisotropies induced by the SrTiO3 substrate.
