Colossal Magnetoelectric Effect in Core–Shell Magnetoelectric Nanoparticles

Nano Letters, 2020
Magnetoelectric coefficient values of above 5 and 2 V cm-1 Oe-1 in 20 nm CoFe2O4-BaTiO3 and NiFe2O4-BaTiO3 core-shell magnetoelectric nanoparticles were demonstrated. These colossal values, compared to 0.1 V cm-1 Oe-1 commonly reported for the 0-3 system, are attributed to (i) the heterostructural lattice-matched interface between the magnetostrictive ...

MAGNETOELECTRIC EFFECTS IN MULTIFERROICS

Izvestia Ufimskogo Nauchnogo Tsentra RAN, 2021
Research of magnetoelectric effects and multiferroic materials, in which these effects are manifested, is among key areas in modern magnetism. This is associated with promising aspects of applying the results to spintronics, orbitronics, and new generation systems for information storage and processing.

On the linear magnetoelectric effect

Journal of Physics: Condensed Matter, 1990
A complete analysis of the linear magnetoelectric (ME) effect is carried out which exploits the PT symmetry of the ME susceptibility tensor alpha . The existing (or 'old') theory in effect considers only the time-reversal antisymmetry of alpha , with the result that it restricts the effect to magnetic crystals.

Magnetoelectric Effects in Antiferromagnetics

Journal of Applied Physics, 1962
Spin-ordered materials may exhibit a magnetic polarization which is proportional to an applied electric field and an electric polarization which is proportional to an applied magnetic field. In this paper a comprehensive discussion is given of the present knowledge of these magnetoelectric (ME) effects.

Magnetoelectric Effect for Phonons

2021
The phonon angular momentum for each mode \(\mathbf {l}_{\sigma }\) is an odd (even) function of phonon wave vector \(\mathbf {k}\) when the system has time-reversal (inversion) symmetry. Thus, to make phonon angular momentum nonzero \(\mathbf {l}_{\sigma }(\mathbf {k})\ne 0\), at least one of these symmetries must be broken.

Magnetoelectric Effect in Polar Superconductors

Physical Review Letters, 1995
The question of how the lack of spatial reflection symmetry can affect properties of a superconductor is investigated. A novel magnetoelectric effect is predicted: The supercurrent in a metal of polar symmetry must be accompanied by the spin polarization of the carriers. The relevance to some known pyro- and antipyroelectric superconductors including a

Multiplied magnetoelectric effect in multi-faceted magnetoelectric composite

Applied Physics Letters, 2014
A four-faceted magnetoelectric (ME) composite consisting of one cuboid bonded Terfenol-D composite and four plates of Pb(Zr,Ti)O3 (PZT) was fabricated. The ME voltage coefficients were measured along the length direction of the composite when PZT plates were parallelly or serially connected.

On the magnetoelectric effect in LiNiPO4

Low Temperature Physics, 2000
It is shown that the “butterfly” magnetoelectric hysteresis loop usually associated with the presence of a spontaneous magnetic moment in a crystal can also be observed in the case of an “angled cross” type of antiferromagnetic ordering of the spins. The magnetoelectric hysteresis observed in LiNiPO4 is explained by the cross-shaped antiferromagnetic ...
