The Verdet constant increases substantially as the mineral approaches cryogenic temperatures.
2.
TGG has a high Verdet constant which results in the Faraday effect.
3.
The Verdet constant for most materials is extremely small and is wavelength dependent.
4.
The highest Verdet constants in bulk media are found in terbium transparency properties and high damage thresholds for laser radiation.
5.
Atomic vapours, however, can have Verdet constants which are orders of magnitude larger than TGG, but only over a very narrow wavelength range.
6.
The Faraday effect is chromatic ( i . e . it depends on wavelength ) and therefore the Verdet constant is quite a strong function of wavelength.
7.
The Verdet constant of ( MgF 2 ) at 632.8 nm is 0.00810 arcmin G & minus; 1 cm & minus; 1.
8.
At 632 nm, the Verdet constant for TGG is reported to be-134 rad / T�m, whereas at 1064 nm it falls to-40 rad / T�m.
9.
Some materials, such as terbium gallium garnet ( TGG ) have extremely high Verdet constants ( H " " 134 rad T " 1 m " 1 ) ( for 632 nm light ).
10.
YIG has a high Verdet constant which results in the Faraday effect, high Q factor in microwave frequencies, low absorption of infrared wavelengths down to 1200 nm, and very small linewidth in electron spin resonance.
