Temperature Dependency of the major permanent magnetic materials

Thermal Expansion coefficients of the magnets:
Thermal expansion anomalies appear near TC and phase transformation temperatures, as well as the spin reorientation temperature for Nd-Fe-B. The thermal anomalies are shown mainly in the c-axis for RE-Co materials. The thermal anomaly behavior is related to the magnitude of spontaneous magnetization, crystal structure and modulus of elasticity.
