Abstract

The nonvolatile behaviors of magnetically correlated anisotropic resistive switching in Co/0.7 Pb(Mg_1/3Nb_2/3)O₃-0.3PbTiO₃ (Co/PMN-PT) multiferroic heterostructures are systematically investigated. When the polarization state of PMN-PT is reversed, a non-volatile anisotropic resistivity switch occurs, corresponding to the non-volatile 90°-rotation of magnetic-easy-axis in Co film owing to the competition between magnetoelastic and interfacial anisotropies. The anisotropic magnetoresistivities (AMR) between two opposite polarization states in a field below anisotropic field also show a 90° phase-shift. While at fields above anisotropic field, the AMR reveals the asymmetric cos²(θ)-like behaviors. The AMR manipulated by electric and magnetic fields is of benefit for studying the magnetization rotation processes.
