Cryogenic temperature characteristics of Verdet constant on terbium gallium garnet ceramics

Abstract

As the first demonstration of Faraday effect in a TGG ceramics, its Verdet constant at 1053 nm is evaluated to be 36.4 rad/Tm at room temperature which is same as that of the single crystal. In addition, the temperature dependence of Verdet constant is obtained experimentally. At liquid helium temperature, it is 87 times greater than that at room temperature.

Faraday effect in Tl3AsS4 crystals

“…This is readily confirmed by a comparison with a number of well-known magnetooptic materials. For example, the Verdet constant is equal to 115 rad/T×m for Sn 2 P 2 S 6 crystals [11], 187 rad / T m [13,14]. They are comparable to that obtained for our crystals.…”

Preparation of (Tb0.8Y0.2)3Al5O12 transparent ceramic as novel magneto-optical isolator material

“…Over the past two decades, several studies have shown that the transparent ceramic may replace its single crystal counterpart because of its excellent properties [9,10] . The TGG ceramic was first reported in 2003 [11] , and recent studies had shown that TGG transparent ceramics exhibited qualities similar to those of single crystals [12,13] . The synthesis of TAG transparent ceramics has also been studied [14] .…”

Kerr and Faraday effects in borate glasses

“…These crystals are not convenient due to their ferroelectric properties and, moreover, their growth is more complicated technologically, when compare with the procedures for obtaining the glasses. On the other hand, magnetically ordered solids which are nontransparent in the visible and ultraviolet spectral ranges also belong to the bulk magnetooptic materials [33][34][35][36]. In the present study we report the results of studies for the electrooptic and magnetooptic properties of LiKB 4 O 7 , Li 2 B 6 O 10 , and LiCsB 6 O 10 glasses.…”
