Ferromagnetic State of LaMnO₃ Interlayer in La_0.7Sr_0.3MnO₃/LaMnO₃/SrRuO₃ Heterostructures

Abstract:

Magnetic state of epitaxial heterostructures La_0.7Sr_0.3MnO₃/LaMnO₃/SrRuO₃ (LSMO/LMO/SRO) was studied by SQUID magnetometer, ferromagnetic resonance (FMR) and polarized neutron reflectometry (PNR) techniques. The fit of PNR and FMR data give us the magnetization of each layer, while the SQUID gives the total magnetization of our structures. The magnetic moment of the LMO layer has the magnetization 4πM_LMO=4.2kGs (2.4 m_B/Mn) at T=140K according to our PNR data fitting.
