Demonstration of a pseudo-magnetization based simultaneous write and read operation in a Co₆₀Fe₂₀B₂₀/Pb(Mg_1/3Nb_2/3)_0.7Ti_0.3O₃ heterostructure.

ABSTRACT: Taking advantage of the magnetoelectric and its inverse effect, this article demonstrates strain-mediated magnetoelectric write and read operations simultaneously in Co₆₀Fe₂₀B₂₀/Pb(Mg_1/3Nb_2/3)_0.7Ti_0.3O₃ heterostructures based on a pseudo-magnetization µ ≡ m_x²- m_y². By applying an external DC-voltage across a (011)-cut PMN-PT substrate, the ferroelectric polarization is re-oriented, which results in an anisotropic in-plane strain that transfers to the CoFeB thin film and changes its magnetic anisotropy H_k. The change in H_k in-turn results in a 90° rotation of the magnetic easy axis for sufficiently high voltages. Simultaneously, the inver
