It introduces a novel self-consistent method to simultaneously study magnetic and lattice ordering in a two-level system, including external influences.

Findings

Magnetization and excited level occupation are calculated self-consistently.

External magnetic field influences the ferromagnetic phase transition.

Energy gap affects the stability of magnetic ordering.

Abstract

Ferromagnetic ordering in a two-level partially excited system is studied in detail. Magnitudes of magnetization (magnetic order parameter) and lattice ordering (excited level occupation number) are calculated self-consistently. The influence of an external magnetic field and excited level gap on the ferromagnetic phase transition is discussed.
