Temperature-Dependent Magnetoelectric Effect from First Principles [PDF]

, 2010
We show that nonrelativistic exchange interactions and spin fluctuations can give rise to a linear magnetoelectric effect in collinear antiferromagnets at elevated temperatures that can exceed relativistic magnetoelectric responses by more than 1 order ...

Linear magnetoelectric electro-optical effect

Physical Review B
In this work, we derive a generalized constitutive relation describing the current response to external electromagnetic fields in electrically biased quantum materials. While our semiclassical Boltzmann approach reveals the existence of electro-optic effects induced by the Berry curvature dipole of Bloch electrons, we also find a wealth of alternative ...

Surface-effect enhanced magneto-electric coupling in FePt/PMN-PT multiferroic heterostructures

AIP Advances, 2017
A series of FePt films with different film thickness are deposited on Pb(Mg1/3Nb2/3)O3–PbTiO3 (PMN-PT) substrates. A standard symmetric ‘Butterfly’ shaped ΔM/M-Edc loops is obtained in 8 nm FePt/PMN-PT heterostrucuture via strain mediated magnetoelectric
