Экспериментальная система для кристального магнитооптического

The magnetic spin effect of the crystal, also called the Faraday effect, has an important position in the optical experiment. Through this experimental system, can observe the Faraday effect of the tested materials, understand the relationship between magnetic current and rotation direction, calculate the Verdet constant of the material, and the validation of Marius's law etc.. When the linearly polarized light passes through a magnetic field at constant or low frequency, the symmetry of the system may be destroyed, and the polarization characteristic of the beam will change. This is the magneto-optical effect. If the magnetic field is parallel to the direction of incident light wave loss occurs, Faraday phenomenon, namely the polarization of the incident wave surface is rotated in a magnetic field, rotation angle is proportional to the strength of the magnetic field and magnetic field, when the reverse rotation of the plane of polarization direction is opposite, this kind of magneto-optical effect called Faraday magneto-optical effect.
