Magnetoelectric coupling in MnTiO3 [PDF]

open access: yes, 2011
We give general arguments that show that the linear magnetoelectric effect in antiferromagnetic materials gives rise to a magnetocapacitance anomaly—a divergence of the dielectric constant at the magnetic ordering temperature TN that appears in an ...

Sinusoidal electromagnon in RMnO3: Indication of anomalous magnetoelectric coupling [PDF]

open access: yes, 2011
The optical spectra in the family of multiferroic manganites RMnO3 is a great puzzle. Current models can not explain the fact that two strong electromagnons are present in the non-collinear spin cycloidal phase, with only one electromagnon surviving the ...

Magnetoelectric coupling in superconductor-helimagnet heterostructures [PDF]

open access: yesPhysical Review B, 2017
The Ginzburg-Landau free energy of a conventional superconductor coupled to a helimagnet is microscopically derived using functional field integral techniques. We show that the spin texture leads to a Lifshitz invariant in the free energy, which couples the momentum density of the superconducting condensate to the magnetization of the helimagnet.

Nonfrustrated magnetoelectric with incommensurate magnetic order in magnetic field

open access: yes, 2007
We discuss a model nonfrustrated magnetoelectric in which strong enough magnetoelectric coupling produces incommensurate magnetic order leading to ferroelectricity. Properties of the magnetoelectric in magnetic field directed perpendicular to wave vector

Designing asymmetric multiferroics with strong magnetoelectric coupling [PDF]

open access: yesPhysical Review B, 2014
Multiferroics offer exciting opportunities for electric-field control of magnetism. Unfortunately, single-phase multiferroics suitable for such applications at room temperature has not been discovered. Here, we propose the concept of a new type of multiferroics, namely, "asymmetric multiferroic".

Magnetoelectric Coupling and Electric Control of Magnetization in Ferromagnet-Ferroelectric-Metal Superlattices

open access: yes, 2009
Ferromagnet-ferroelectric-metal superlattices are proposed to realize the large room-temperature magnetoelectric effect. Spin dependent electron screening is the fundamental mechanism at the microscopic level.

Landau Theory of Domain Wall Magnetoelectricity [PDF]

open access: yes, 2010
We calculate the exact analytical solution to the domain wall properties in a multiferroic system with two order parameters that are coupled bi-quadratically.

Magnetoelectric coupling in noncollinear ferrimagnets

open access: yesMagnetic resonance in solids, 2019
© Kazan Federal University (KFU). The analytical expressions for the energy coupling of exchange coupled spins with electric field, induced by odd crystal field has been derived in the third order perturbation theory, combining the action of electric field, spin-orbit and exchange interactions.

Magnetic and microwave properties of (Ni,Co)Fe2O4-ferroelectric and (La,Ca,Sr)MnO3-ferroelectric multilayer structures

open access: yes, 2003
Structural, magnetic and ferromagnetic resonance characterization studies have been performed on lay-ered ferromagnetic-ferroelectric oxides that show strong magnetoelectric coupling. The samples contained thick films of ferrites or substituted lanthanum
