Elastic domains in antiferromagnets
Efim A. Brener, and V.I. Marchenko
TL;DR
This paper investigates how elastic and magnetic interactions in antiferromagnetic crystals attached to substrates lead to periodic domain structures, analyzing their behavior under external magnetic fields and how their properties depend on magnetic field strength.
Contribution
It introduces a model for periodic domain structures in antiferromagnets influenced by magnetoelastic coupling and examines their magnetic field dependence, including equilibrium period and domain concentrations.
Findings
Magnetic field affects the equilibrium period of domain structures.
Domain concentrations vary with external magnetic field.
The behavior of domain structures under magnetic fields is characterized.
Abstract
We consider periodic domain structures which appear due to the magnetoelastic interaction if the antiferromagnetic crystal is attached to an elastic substrate. The peculiar behavior of such structures in an external magnetic field is discussed. In particular, we find the magnetic field dependence of the equilibrium period and the concentrations of different domains.
