This empirical proportionality constant varies with wavelength and temperature and is tabulated for various materials.

TGG (Terbium Gallium Garnet) single crystal is currently the best and widely used magneto-optical material in Faraday rotator and isolator due to its extremely high Verdet constants in the range of 400nm-1100nm(excluding 475-500nm).

The magnitude of the Verdet constant is 0.838 min/cm Oe at the wavelength of 450 nm. This value is large compared with those reported for other glasses containing trivalent rare-earth ions.

The Faraday effect can, however, be observed and measured in a Terbium-doped glass with Verdet constant as low as (≈ −20 rad/(T·m) for 632 nm light). Similar isolators are constructed for microwave systems by using ferrite rods in a waveguide with a surrounding magnetic field.

A Verdet constant of 15.18 rad/T/m at 1950 nm with the figure of merit of more than 8.72 rad/T, which is the highest value reported in glass materials at this wavelength, was measured. A Verdet constant of 15.18 rad/T/m at 1950 nm with the figure of merit of more than 8.72 rad/T, which is the highest value reported in glass materials at this wavelength, was measured. Heavily terbium‐doped boron‐silicate glasses (Tb3+10.4 at. %) with a Verdet constant (632.8 nm, room temperature) as large as −0.338 min/Oe cm, 38% larger than that of the famous FR‐5 glasses, have tionality constant and is called a Verdet constant.

Compared to the host glass, Fe3O4 nanoparticles doped glasses shown enhanced Faraday Effect in term of Verdet constant and will have potential application in magneto-optical devices. Effect of Magnetite Nanoparticles Doped Glass with Enhanced Verdet Constant for Magnetic Optical Current Transducer Applications | Scientific.Net

The Verdet constant is an optical property named after the French physicist Émile Verdet.It describes the strength of the Faraday effect for a particular material. For a constant magnetic field parallel to the path of the light, it can be calculated by:

The goal of the experiment was to measure the Verdet Constant for the light int glass sample and compare it The Verdet constant itself depends on the m edium, its temperature and the frequency of the polarized light. (Note: the conventional symbol for the Verdet constant is: V. To avoid confusion with voltage readings, we switched the symbol to the Greek letter ν.) field component in the direction of the light propagation and V is the Verdet constant for the material (MKS units: radian/Tesla meter). This empirical proportionality constant varies with wavelength and temperature and is tabulated for various materials. The Verdet Constant, V, depends on the dispersion of the refractive index, dn/d where n The Verdet constant of the Faraday rotation has been determined experimentally as a function of wavelength for optical glasses at 20 degree(s)C in the visible spectral range. Data have been analyzed for 40 different optical glasses. Very large values of the Verdet constant have been measured for the heavy flint glasses such as SF 59, SF 58, SF 57, and SF 6. On the other hand, very low values TGG has twice the Verdet constant of a Terbium-doped glass.

One example of material consisting of paramagnetic ions is terbium, which includes terbium doped glass (TDG) and ter-bium gallium garnet (TGG) as MO materials. The Faraday Rotator Glass Faraday rotator glass is a kind of magneto-optical glasses with good transmittance in the visible and infrared range（520～1400nm）. Faraday rotator glass is more suitable for medium and low power level lasers, and is cheaper compared with the other magneto-optic crystals such as TGG,TSAG.
