Features of the flexomagnetoelectric effect in an external magnetic field

TL;DR

This paper explores how external magnetic fields affect the flexomagnetoelectric effect in ferromagnetic films, revealing that magnetic field strength and direction can modulate the effect and even reverse the interaction nature with electric fields.

Contribution

It demonstrates the magnetic field's ability to control and switch the flexomagnetoelectric interaction in uniaxial ferromagnetic films, a novel insight into magnetoelectric coupling.

Findings

Magnetic field can strengthen or weaken the flexomagnetoelectric effect.

Reversing the magnetic field can switch the interaction from attraction to repulsion.

Magnetic field direction influences the behavior of domain boundaries.

Abstract

The paper investigates the influence of the magnetic field on the behavior of 180-degree domain boundaries in a uniaxial ferromagnetic film with inhomogeneous magnetoelectric interaction. It is shown that, depending on the magnitude and direction of the field, it is possible to strengthen or weaken the flexomagnetoelectric effect in the sample under study. In addition, it was found that in the reverse field, the effect of switching the nature of the interaction of the electric field source with the domain wall from attraction to repulsion is possible.
