Faraday rotation and the magnetocaloric effect in the Tb3Ga5O12 terbium gallium garnet at low temperatures in strong magnetic fields

Abstract

The magnetocaloric effect and the Faraday rotation in a paramagnetic cubic crystal of terbium gallium garnet in strong magnetic fields oriented along different crystallographic directions are calculated theoretically. It is demonstrated that, in strong magnetic fields, the magnetocaloric effect and the Faraday effect are characterized by strong anisotropy, which disappears in weak magnetic fields.
