Metastability in the formation of Condon domaines

TL;DR

This paper investigates metastability and phase transitions in Condon magnetic domains within a three-dimensional electron gas, highlighting the emergence of multiple domains and complex phase diagrams involving first- and second-order transitions.

Contribution

It introduces the concept of metastability effects and describes the possibility of first-order phase transitions in a two-frequency de-Haas-van Alphen oscillation scenario.

Findings

Multiple magnetic domains can form in aluminum due to metastability.

The phase diagram shows both first- and second-order phase transitions.

Two additional domains appear in the metastable region.

Abstract

Metastability effects in the formation of Condon non-spin magnetic domains are considered. A possibility for the first-order phase transition occurrence in a three-dimensional electron gas is described in the case of two-frequency de-Haas-van Alphen magnetization oscillations originating from two extremal cross sections of the Fermi surface. The appearance of two additional domains is shown in the metastable region in aluminum. The phase diagram temperature-magnetic field exhibits the presence of second-order and first- order phase transitions in the two-frequency case.
