Electric Field Tuning Non-volatile Magnetism in Half-Metallic Alloys Co(2)FeAl/Pb(Mg(1/3)Nb(2/3))O(3)-PbTiO(3) Heterostructure

We reported the non-volatile electric field-mediated magnetic properties in the half-metallic Heusler alloy Co(2)FeAl/Pb(Mg(1/3)Nb(2/3))O(3)-PbTiO(3) heterostructure at room temperature. The remanent magnetization with different applied electric field along [100] and [01-1] directions was achieved,...

Descripción
Sumario:We reported the non-volatile electric field-mediated magnetic properties in the half-metallic Heusler alloy Co(2)FeAl/Pb(Mg(1/3)Nb(2/3))O(3)-PbTiO(3) heterostructure at room temperature. The remanent magnetization with different applied electric field along [100] and [01-1] directions was achieved, which showed the non-volatile remanent magnetization driven by an electric field. The two giant reversible and stable remanent magnetization states were obtained by applying pulsed electric field. This can be attributed to the piezostrain effect originating from the piezoelectric substrate, which can be used for magnetoelectric-based memory devices.
