Garcia et al.have recently reported on the ferroelectric control of spin polarization in an artificial multiferroic heterostructure1, i.e. Fe/BaTiO3/La2/3Sr1/3MnO3 (Fe/BTO/LSMO). This contribution is considered as a breakthrough in the field of spintronics since it opens new perspectives to create a magnetoelectric coupling which can be obtained in heterostructures combining an ultrathin ferroelectric layer between of two ferromagnetic electrodes. It has been for the first time demonstrated experimentally the opportunity to tune the spin polarization by an electric field in these artificial multiferroic tunnel junctions. Read more »
