Abstract :
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). As we know that there is a competition between electron tunneling and Kondo scattering in MTJs. 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. 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 La0.7Sr0.3MnO3/BaTiO3/ La0.7Sr0.3MnO3 (LSMO/BTO/LSMO) MFTJ.
