An investigation on the terbium gallium garnet magneto-optic properties of under high magnetic field

The superexchange interaction on a magnetic ion may be represented by an effective field Hm =λM in some paramagnetic materials, here λis the coefficient of effective field and M = XHe with X being the magnetic susceptibility and He being the applied field. The variation of the equivalent λX with the...

Summary:The superexchange interaction on a magnetic ion may be represented by an effective field Hm =λM in some paramagnetic materials, here λis the coefficient of effective field and M = XHe with X being the magnetic susceptibility and He being the applied field. The variation of the equivalent λX with the dynamic applied field is given and the crystal field-splitting levels of the excited configuration 4f75d1 of the Tb3＋ ion are calculated in the Tb3Ga5O12. By means of the effective field Hm and the applied field He, the Faraday rotation of Tb3CasO12 at 6 K and 41 K, under the high magnetic field and at 0.63μm wavelength, are presented. Our calculated results are in agreement with the experimental data.
