摘要

We have optimized the perpendicular magnetic anisotropy of piezoelectric/ferromagnetic and dielectric/ferromagnetic heterostructures based on Co/Pt multilayers. These hybrid systems are promising for electric field control of magnetism for applications to ultra-low power spintronics devices. Epitaxial (PbMg_1/3Nb_2/3O₃)_0.7- (PbTiO₃)_0.3 has been used for the piezoelectric layer and several dielectric layers (MgO, Al₂O₃, HfO₂, Ta₂O₅ and TiO₂) have been tested. We show that for both heterostructures perpendicular magnetic anisotropy of Co/Pt multilayers can be obtained with small coercivity.
