Terbium gallium garnet - Wikipedia
Terbium gallium garnet (TGG) is a kind of synthetic garnet, with the stone composition Tb3Ga5O12. This is a Faraday rotator material with excellent transparency properties and is very resistant to laser damage. TGG can be used in optical isolators for laser systems, in optical circulators for fiber optic systems, in optical modulators, and in current and magnetic field sensors.

Terbium Gallium Garnet (TGG) is an magneto-optical crystal with a high level of thermal conductivity for Faraday rotators and isolators.
Terbium Gallium Garnet - TGG
Terbium Gallium Garnet (TGG) is a crystal material for optical isolator devices. Optical isolator devices make use of the non-reciprocal Faraday effect in TGG. The Faraday effect is the rotation of the plane of polarization of a light beam as it is transmitted through a material in the presence of an external magnetic field coaxial with the light.

Magnetic linear birefringence and dichroism are investigated for the paramagnetic terbium gallium garnet (TGG) single crystal in the temperature range 8–100 K. The reciprocal nature is confirmed for the linear birefringence. Furthermore a theoretical model is validated that describes the intermixing of linear and circular birefringence.
