Strong non-volatile voltage control of magnetism in magnetic/antiferroelectric magnetoelectric heterostructures

Strong magnetoelectric coupling was demonstrated in magnetic/antiferroelectric heterostructures of FeGaB/Pb(La,Sn,Zr,Ti)O3, which exhibited a voltage induced coercive field change of 7–10 Oe and ferromagnetic resonance field shifts by ∼80 Oe. Nonvolatile voltage induced magnetization switching and f...

Beschreibung
Zusammenfassung:Strong magnetoelectric coupling was demonstrated in magnetic/antiferroelectric heterostructures of FeGaB/Pb(La,Sn,Zr,Ti)O3, which exhibited a voltage induced coercive field change of 7–10 Oe and ferromagnetic resonance field shifts by ∼80 Oe. Nonvolatile voltage induced magnetization switching and ferromagnetic resonance field shift in FeGaB were realized based on the ferroelectric-antiferroelectric phase transition in Pb(La,Sn,Zr,Ti)O3. The nonvolatile strong voltage control of magnetism in magnetic/antiferroelectric heterostructures has great implications in compact and power efficient spintronics and RF/microwave components.
