Title: Electric-field induced strain modulation of magnetization in Fe-Ga/Pb(Mg{sub 1/3}Nb{sub 2/3})-PbTiO{sub 3} magnetoelectric heterostructures

Abstract

Magnetostrictive Fe-Ga thin layers were deposited on 〈110〉-oriented Pb(Mg{sub 1/3}Nb{sub 2/3})-30%PbTiO{sub 3} (PMN-30%PT) substrates by pulsed laser deposition. The as-prepared heterostructures showed columnar arrays aligned in the out-of-plane direction. Transmission electron microscopy revealed nanocrystalline regions within the columnar arrays of the Fe-Ga film. The heterostructure exhibited a strong converse magnetoelectric coupling effect of up to 4.55 × 10{sup −7} s m{sup −1}, as well as an electric field tunability of the in-plane magnetic anisotropy. Furthermore, the remanent magnetization states of the Fe-Ga films can be reversibly and irreversibly changed by external electric fields, suggesting a promising and robust application in magnetic random access memories and spintronics.
