"large electric current switching magnetization vectors during writing, resulting in Joule heating/ energy consumption, overcome by multiferroic heterostructure with magnetization vectors switched by electric field... heterostructure responds with large amount of converse magnetoelectric coupling coefficient; causing strong magnetization... ultra-thin vanadium layer between ferromagnetic/ piezoelectric layers enabling magnetic anisotropy Co2FeSi layer. control... non-volatile binary state achieved at zero electric field"
