Magnetic refrigeration uses the magnetocaloric effect of magnetic refrigeration materials to discharge energy to the outside world during isothermal magnetization and absorb heat from the outside during demagnetization, so as to achieve the purpose of refrigeration. The refrigerant in magnetic refrigeration technology is a solid magnetic material. When the magnetic material is magnetized, the magn...

TGG crystal is the best magneto-optical material for Faraday rotator and isolator Faraday rotator is a magneto-optical device based on Faraday magneto-optical effect. It can rotate the polarization direction of incoming ray polarized light by a certain angle, and the rotation direction is only related to the internal magnetic field and independent of the light passing direction. The rotation angle...
