Morphology of Condon Domains Phase in Plate-Like Sample

TL;DR

This paper theoretically investigates the morphology of Condon domains in a plate-like sample, focusing on phase transitions, temperature, magnetic field effects, and impurity influences within the inhomogeneous diamagnetic phase related to the dHvA effect.

Contribution

It provides a theoretical analysis of the Condon domains' morphology, phase diagrams, and the effects of temperature, magnetic field, and impurities on the inhomogeneous diamagnetic phase.

Findings

Phase diagrams of inhomogeneous diamagnetic phase are calculated.

First order phase transitions govern the structure within each dHvA oscillation period.

Sample impurities and temperature significantly influence the phase morphology.

Abstract

Based on Shoenberg assumption of magnetic flux density dependence of diamagnetic moments which accounts for an instability of strongly correlated electron gas at the conditions of dHvA effect and diamagnetic phase transition (DPT) to non-uniform phase, we investigate the morphology of the Condon domains (CD) in plate-like sample theoretically. At one period of dHvA oscillations the intrinsic structure of inhomogeneous diamagnetic phase (IDP) is governed by the first order phase transitions between different non-uniform phases similar to the high-anisotropy magnetic systems of spin origin, and strongly affected by temperature, magnetic field and impurity of the sample due to the electron correlations. The phase diagrams of evolution of IDP with temperature and small-scale magnetic field in every period of dHvA oscillations are calculated.
