Magnetization, isothermal

Thus, repeated cycles of isothermal magnetization and adiabatic demagnetization lead to the desired cooling of the salt.

The molar isothermal magnetic susceptibility becomes expressed as follows... 

The magnetic susceptibility is introduced as a thermodynamic quantity which requires a partial differentiation of the magnetisation according to the applied field. This differential (isothermal) magnetic susceptibility differs from the frequent definition of mean magnetic susceptibility if the behaviour of the magnetic material is nonlinear.

The above physical quantity, denoted by AS and expressed in J K , is called the field-induced isothermal magnetic entropy change or simply isothermal magnetic entropy change. 

This variation, called the adiabatic temperature change calculation of the isothermal magnetic entropy change, is based on the following Maxwell relation ... 

For most paramagnetic and ferromagnetic materials, the isothermal magnetic entropy change per unit of magnetic induction usually ranges from 1 to 4 J.kg .K .T .
