摘要
In a strong magnetic field, the magnetic susceptibility chi and equivalent magnetic susceptibility lambda chi of some paramagnetic materials depend sensitively on the applied field H-e. Here lambda is the coefficient of the effective field H-m, which relates to the superexchange interaction between the electrons in different magnetic ions. We present the forms of the adiabatic equivalent lambda chi and the effective field H-m. The adiabatic magneto-caloric and magneto-optical effects of paramagnetic terbium gallate garnet Tb3Ga5O12 are calculated at 6 K in strong magnetic fields. Our calculated results are in agreement with the experimental data.
