论文摘要
我们以频率从$ 300 \,\ Mathrm {ghz} $到$ 1 \,\ Mathrm {thz} $,并确定材料响应的材料响应,我们报告了Gadolinium Garnet(GGG)和Gadolinium Scandium Garnet(SGGG)的磁光反应。在此频率窗口中,材料表现出非分散性和低损坏的光学响应。在低温下,在(S)GGG样品中发现了明显的Thz Faraday旋转。如此强大的陀螺症反应可能与GD $^{3+} $ ions的高旋转顺磁状态有关。确定材料响应张量的模型,以及Verdet和磁化常数。
We report the magneto-optical response of Gadolinium Gallium Garnet (GGG) and Gadolinium Scandium Gallium Garnet (SGGG) at frequencies ranging from $300 \, \mathrm{GHz}$ to $1 \, \mathrm{THz}$, and determine the material response tensor. Within this frequency window, the materials exhibit nondispersive and low-loss optical responses. At low temperatures, significant THz Faraday rotations are found in the (S)GGG samples. Such strong gyroelectric response is likely associated with the high-spin paramagnetic state of the Gd$^{3+}$ ions. A model of the material response tensor is determined, together with the Verdet and magneto-optic constants.
