Anomalous magneto-transports of La_(0.67)Sr_(0.33)MnO_3/2DES-LaAlO_3/SrTiO_3

摘要

Very recently, Rashba-Edelstein effect driven efficient spin-to-charge and charge-to-spin conversion have been demonstrated in the two-dimensional electron system (2DES) at the hetero-interface between LaAlO_3 (LAO) and SrTiO_3 (STO). These observations suggest that the 2DES at LAO/STO is a promising material as the spin detector and spin generator. In order to clarify the interaction between the generated spin and magnetization of a ferromagnetic layer adjacent to LAO/STO by electrical means, it is important to understand the magneto-transport such as planar Hall effect (PHE) and anisotropic magnetoresistance (AMR) of the ferromagnetic layer. Here we report PHE and AMR of a ferromagnetic oxide, La_(0.67)Sr_(0.33)MnO_3 (LSMO) on an LAO/STO.
