Inherent Spin–Polarization Coupling in a Magnetoelectric Vortex

Nano Letters, 2022
Solid-state materials are currently being explored as a platform for the manipulation of spins for spintronics and quantum information science. More broadly, a wide spectrum of ferroelectric materials, spanning from inorganic oxides to polymeric systems such as PVDF, present a different approach to explore quantum phenomena in which the spins are set ...

Magnetoelectric Coupling in Disordered Multiferroics

Ferroelectrics, 2012
Higher order magnetoelectric effects dominate in disordered multiferroics with broken translational symmetry such as multiglassy Sr0.98Mn0.02TiO3, antiferromagnetic quantum paraelectric EuTiO3, relaxor ferroelectric antiferromagnetic Pb(Fe0.5Nb0.5)O3, and antiferroelectric antiferromagnetic CuCr1-xInxP2S6.

Grüneisen parameters in the quantum paramagnet with the magnetoelectric coupling

Low Temperature Physics, 2022
It is shown theoretically that magnetic Grüneisen parameter for the quantum orthorhombic paramagnet manifests features similar to the ones observed in many-body quantum spin systems at critical points. For the paramagnet with the strong coupling between the spin and electric subsystems, we have introduced the electric Grüneisen parameter, which is the ...

Enhanced magnetoelectric coupling in stretch-induced shear mode magnetoelectric composites

Journal of the Korean Ceramic Society, 2021
Magnetoelectric (ME) laminates consisting of Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT)-based single crystals have recently attracted significant interest owing to their excellent piezoelectric properties. Particularly, ME laminates with d15-mode single crystals exhibit the strongest ME coupling, but the fabrication of ME laminates with 15 shear modes is ...

Magnetoelectric coupling in nanocrystalline Pb0.82La0.18TiO3

Applied Physics Letters, 2012
The combined effect of Pb vacancies and La dopant can induce ferromagnetism below 75 K for Pb0.82La0.18TiO3 plates annealed at 700,1000, and 1200 °C for 1 h. Pb0.82La0.18TiO3 plates annealed at 1000 °C for 1 h show the coexistence of ferromagnetism resulting from oxygen vacancies at/near surfaces of nanograins and ferroelectricity near room temperature.

Effect of magnetic bias field on magnetoelectric coupling in magnetoelectric composites

Journal of Applied Physics, 2003
The effect of dc magnetic bias field on the magnetoelectric coupling of a two-component magnetoelectric composite structure is investigated numerically using the finite-element method, in which the nonlinear magnetostress coupling for the magnetostrictive component is taken into account. It is shown that the magnetostress coupling coefficient increases

Microwave Magnetoelectric Couplings in FeCoB/Piezoelectric Bilayers

IEEE Transactions on Magnetics, 2013
This paper deals with the study of magnetoelectric structures which could allow the emergence of a new class of microwave tunable devices. Our interest was focused on composite magnetoelectric structures which associate piezoelectric substrates and magnetostrictive layers in order to get a variation of microwave permeability thanks to an electric field.

New relativistic Hamiltonian: the angular magnetoelectric coupling

SPIE Proceedings, 2016
Spin-Orbit Coupling (SOC) is a ubiquitous phenomenon in the spintronics area, as it plays a major role in allowing for enhancing many well-known phenomena, such as the Dzyaloshinskii-Moriya interaction, magnetocrystalline anisotropy, the Rashba effect, etc.

On the Theory of Magnetoelectric Coupling in LiCu2O2

Journal of Experimental and Theoretical Physics, 2019
A microscopic theory is proposed for coupling of copper spins with an external electric field in the magnetically ordered phase of LiCu2O2. The expressions are derived for the dipole moment components of exchange-coupled pairs of copper spins, as well as expressions for describing the macroscopic polarization in terms of the angles determining spatial ...
