Theoretical Investigation of Magnetoelectric Coupling in MFe2O4/PbZ(0.5)T(0.5)O(3)/MFe2O4 (M = Ni, Co) Heterostructure

Abstract : Magnetoelectric materials that allow magnetic-field control of electric polarization are promising candidates for high-density data storage and spintronic devices. In this paper, the ferroelectric, magnetic, and magnetoelectric properties of NiFe2O4/PbZ(0.5)T(0.5)O(3), CoFe2O4/PbZ(0.5)T(0.5)O(3), NiFe2O4/PbZ(0.5)T(0.5)O(3)/CoFe2O4, and NiFe2O4/PbZ(0.5)T(0.5)O(3)/NiFe2O4 heterostructures have been carried out using the Monte Carlo simulation in the framework of the Heisenberg model. The effects of the temperature on magnetization, electric polarization, and their susceptibilities were examined. The calculated interfacial magnetoelectric coupling interaction J(me) for NiFe2O4/PbZ(0.5)T(0.5)O(3) and CoFe2O4/PbZ(0.5)T(0.5)O(3) interfaces permitted to predict the magnetoelectric voltage coefficient for these heterostructures and controlling the polarization via a magnetic field. Interestingly, a high magnetoelectric voltage coefficient of 650 and 1405 mV cm(-1) Oe(-1) was predicted in NiFe2O4/PbZ(0.5)T(0.5)O(3)/CoFe2O4 and NiFe2O4/PbZ(0.5)T(0.5)O(3)/NiFe2O4, respectively. Moreover, the effect of J(me) on M-H and P-H hysteresis loops and the magnetoelectric voltage coefficient was studied.
