Quantum oscillations in antiferromagnetic conductors with small carrier pockets

TL;DR

This paper explores how magnetic quantum oscillation data, combined with symmetry considerations, can precisely identify the location of small carrier pockets in the Brillouin zone of antiferromagnetic conductors.

Contribution

It introduces a method to constrain or determine the position of carrier pockets using oscillation data and symmetry arguments in antiferromagnetic materials.

Findings

Oscillation data combined with symmetry narrows down pocket locations.

Method can potentially identify the exact position of carrier pockets.

Provides a new approach for analyzing electronic structures in antiferromagnets.

Abstract

I study magnetic quantum oscillations in antiferromagnetic conductors with small carrier pockets and show that combining the oscillation data with symmetry arguments and with the knowledge of the possible positions of the band extrema may allow us to greatly constrain or even uniquely determine the location of a detected carrier pocket in the Brillouin zone.
