Diamagnetic Phase Transition and Phase Diagrams in Beryllium

TL;DR

This paper proposes a model for diamagnetic phase transition in beryllium considering its quasi-2D Fermi surface, explaining experimental observations of non-homogeneous phases and Condon domain formation under strong dHvA effects.

Contribution

It introduces a new model that accounts for the quasi-2D Fermi surface of beryllium, explaining the observed phase transition and domain structures.

Findings

The model accurately explains recent experimental data.

It shows the instability of homogeneous phase under strong dHvA effects.

It predicts the formation of Condon domains in beryllium.

Abstract

The model of diamagnetic phase transition in beryllium which takes into account the quasi 2-dimensional shape of the Fermi surface of beryllium is proposed. It explains correctly the recent experimental data on observation of non-homogeneous phase in beryllium at the conditions of strong dHvA effect when the strong correlation of electron gas results in instability of homogeneous phase and formation of Condon domain structure.
