Application of GGG Crystal in magnetic refrigeration
Magnetic refrigeration is to use the magnetocaloric effect of magnetic refrigeration materials, in the isothermal magnetization is to discharge energy to the outside world, demagnetization to absorb heat from the outside world, so as to achieve the purpose of refrigeration. When the magnetic material is magnetized, the order degree of magnetic moment increases, the magnetic entropy decreases, the temperature rises and the heat is released to the outside world; During demagnetization, the order degree of magnetic moment decreases, the magnetic entropy increases, the temperature decreases and the heat is absorbed from the outside.

TGG crystal is the best magneto-optical material for Faraday rotator and isolator
Faraday rotator is a kind of magneto-optical device based on Faraday magneto-optical effect. It can rotate the polarization direction of the incoming polarized light by a certain angle, and the rotation direction is only related to the internal magnetic field, and has nothing to do with the light passing direction. The rotation angle of Faraday rotator is 45 ° Or 90 °。 Will 45 ° The polarizer is placed on two plates at 45 ° The optical isolator is formed between the polarizers. Optical isolator is a kind of magneto-optical device with one-way light transmission. It is widely used in laser amplification system, mode-locked laser and laser measurement equipment.
