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 ...

Theoretical Modelling on the Magnetization by Electric Field Through Product Property. [PDF]
, 2006 Multilayer composites of piezoelectric and magnetostrictive materials can be designed to exhibit the magnetoelectric (ME) effect. This ME effect can be realised as an electric polarisation induced by a magnetic field (called MEH effect) or a ...

Dynamical Magnetoelectric Coupling in Multiferroic BiFeO3 [PDF]
International Journal of Thermophysics, 2011 In this study, the magnon excitations in multiferroic BiFeO3 (BFO) have been discussed. The studies are based on the spin wave theory and Katsura’s model. The influence of the spin wave excitations on the terahertz absorption is discussed. The antiferromagnetic and ferroelectric interactions in multiferroic BFO were included using an effective fermion ...

Magnetoelectricity at room temperature in Bi0.9-xTbxLa0.1FeO3 system
, 2004 Magnetoelectric compounds with the general formula, Bi0.9-xRxLa0.1FeO3 (R =Gd, Tb, Dy, etc.), have been synthesized. These show the coexistence of ferroelectricity and magnetism, possess high dielectric constant and exhibit magnetoelectric coupling at ...

Magnetoelectric Coupling Based on Protons in Ammonium Sulfate
The Journal of Physical Chemistry C, 2020 Most ferroelectric crystals have their own set of unique characteristics and ammonium sulfate (NH$_4$)$_2$SO$_4$ is no exception. We report on two previously unidentified features in ammonium sulfate: 1) that there are at least two successive transitions instead of one occurring at the Curie temperature $T$$_C$ = 223 K according to dielectric constant ...

Magnetoelectric coupling of a magnetoelectric flux gate sensor in vibration noise circumstance [PDF]
AIP Advances, 2018 A magnetoelectric (ME) flux gate sensor (MEFGS) consisting of piezoelectric PMN-PT single crystals and ferromagnetic amorphous alloy ribbon in a self-differential configuration is featured with the ability of weak magnetic anomaly detection. Here, we further investigated its ME coupling and magnetic field detection performance in vibration noise ...

An Effective Model of Magnetoelectricity in Multiferroics $RMn_2O_5$
, 2007 An effective model is developed to explain the phase diagram and the mechanism of magnetoelectric coupling in multiferroics, $RMn_2O_5$. We show that the nature of magnetoelectric coupling in $RMn_2O_5$ is a coupling between two Ising-type orders, namely,
