Abstract:

Magnetization of free electron gas for the entire regime is an ideal example for the teaching of thermodynamics and
statistical mechanics et al. The entire regime includes degenerate and non-degenerate, classical and quantum, non-relativistic and relativistic, low magnetic field and high magnetic field et al. From this, students can understand the conception of physics and the differences between application range of physical theory. The relativistic parts about magnetization of electron gas come from the results of author, which can be referenced from corresponding references. However, the magnetic phase transition in this paper is also an ideal example for the teaching and the study of general phase transitions.

Key words: magnetization, magnetic moment of spin, Landau quantization, magnetic phase transition
