摘要：

The temperature dependence of the Faraday effect in TbIG was investigated in the infrared where the rotation αφ does not depend on frequency. It was shown that besides the change in the sign of αφ at the compensation point, there is another change in the sign of αφ at T = 110°K. The temperature dependence of αφ agrees qualitatively with its theoretical behavior obtained in the infrared region from the off-diagonal components of permeability tensor [μ]. For the quantitative agreement of the theoretical and experimental values of αφ, it is necessary to assume that the g-factor of Tb3+ diminishes at low temperatures. The temperature dependence of the g-factor of the Tb3+ ion in TbIG was determined, It was shown that in Bi0.24Ca2.76Fe 3.62V1.38O12 at λ > 4 μ the Faraday effect is positive and independent of λ. The Faraday effect in the garnet has different signs in the infrared and visible regions. This fact is in accordance with the exchange mechanism of the Faraday effect observed in garnets in the infrared. © 1968 The American Institute of Physics.
