Abstract

A complete description of the thermodynamics of the phases of a magnetized, degenerate electron gas is obtained by calculating a generalized free energy as a function of its natural variablesT, μ,H from the exact (nonanalytic) equations of state. This gives a detailed description of the phase transitions into magnetic and density domains around each Landau level. An application to degenerate stars is sketched. Suggested direct and indirect methods for observing these domains in metals and in stars will be briefly reviewed. The inseparably connected degeneracy-inhibition effect could have observable effects on stellar structure for strong enoughB.
