Electric-field induced strain modulation of magnetization in Fe-Ga/Pb(Mg1/3Nb2/3)-PbTiO3 magnetoelectric heterostructures

“…1,2 The most commonly and intensively studied material architectures are two-phase ferromagnetic (FM)/ferroelectric (FE) heterostructures, as they offer fundamental and technological significance. [3][4][5][6][7][8][9][10][11] In these heterostructures, the coupling between electric and magnetic orderings is achieved by electric field induced strain, through the combination of inverse piezoelectric effect and magnetostriction at the interface. Electric field tunability of magnetization is particularly appealing because of its potential attributes that meet the requirements of high density magnetic data storage at small length scales.…”

Domain rotation induced strain effect on the magnetic and magneto-electric response in CoFe2O4/Pb(Mg,Nb)O3-PbTiO3 heterostructures

“…[1][2][3][4][5] Coupling between ferroelectric (FE) and ferromagnetic (FM) subsystems provides additional degrees of freedom to control either the polarization or magnetization with H and E, respectively. Although room temperature magnetoelectric effect has been found in a series of single phase materials, such as bulk Ba 3 Co 2 Fe 24 O 41 (Ref.…”

“…1 Piezoelectric single crystals have been widely used as substrates due to a good crystal lattice parameter matching with most functional oxides and due to their large electromechanical coupling coefficients. 5,14,15 Significant effort has been placed on the study of electric field-induced strains in Pb-based piezoelectric crystals due to their applications in sensors and transducers.…”
