Absoultly there is also temperature dependence of the Faraday rotation when shift to other wavelengths. However, the transparency window of this material is in the 1550 nm wavelength range. When moving to shorter wavelengths, the absorption of this material increases sharply, making them less practical for photonic device applications.
How will the temperature dependence of the Faraday rotation hysteresis loops of Dy:CeYIG thin films change when moving to another wavelength range? Is there any dependence on the wavelength?
