Non-reciprocity in elastic unpolarized neutron scattering by systems with non-coplanar magnetic structure

TL;DR

This paper theoretically demonstrates that elastic unpolarized neutron scattering by systems with non-coplanar magnetic structures violates reciprocity, with specific analysis on magnetic mirrors and vortex-state ferromagnets.

Contribution

It introduces a theoretical framework showing reciprocity violation in neutron scattering by non-coplanar magnetic systems, including practical examples.

Findings

Reciprocity does not hold for unpolarized neutron scattering in these systems.

Analysis of scattering by magnetic mirrors and vortex-state ferromagnets.

Theoretical demonstration of non-reciprocal behavior in specific magnetic configurations.

Abstract

The paper provides a theoretical analysis for elastic unpolarized neutron scattering by systems having a non-coplanar magnetic induction spatial distribution. It is shown that reciprocity does not hold for neutron scattered by these systems. The scattering of unpolarized neutrons by a system of three magnetic mirrors and by a ferromagnetic particle in a "vortex" state is also explored.
