Morphology of Condon Domains Phase in Plate-Like Sample

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.
