On the absence of conduction electrons in the antiferromagnetic part of the phase-separated states in magnetic semiconductors

TL;DR

This paper theoretically investigates phase-separated states in magnetic semiconductors, showing that at zero temperature, the lowest energy configuration excludes conduction electrons from the antiferromagnetic regions.

Contribution

It introduces a calculation of phase-separated state energies considering conduction electrons in antiferromagnetic parts, revealing the absence of electrons in the ground state.

Findings

Minimum energy phase is a droplet with no conduction electrons in antiferromagnetic regions.

At T=0, conduction electrons are energetically unfavorable in the antiferromagnetic phase.

The study clarifies the electronic structure of phase-separated magnetic semiconductors.

Abstract

We have calculated the energies of the phase-separated states for degenerate antiferromagnetic semiconductors including the possibility of the existence of conduction electrons in the antiferromagnetic part of the phase-separated states. It is demonstrated that, at T=0, the minimum energy corresponds to a droplet phase with absence of electrons in the antiferromagnetic part.
