Kondo effect on the transport properties in the multiferroic tunnel junction of La0.7Sr0.3MnO3/BaTiO3/La0.7Sr0.3MnO3

The Kondo effect, one of the most interesting topics in condensed matter physics, shows significant influences on the transport behaviors in magnetic tunnel junctions (MTJs).[1] As we know that there is a competition between electron tunneling and Kondo scattering in MTJs.[2] However, it is not clear how Kondo effect will affect the transport properties of a multiferroic tunnel junction (MFTJ), a MTJs with a ferroelectric material as the tunnel barrier.[3,4] As a ferroelectric polarization may manipulate the Kondo effect, we here attempt to investigate these issues by studying the temperature-dependent and polarization-tuned transport properties in the La
