Magnetization properties under applied magnetic field with MO. (a) Faraday loop of Bi:RIG films at room temperature with garnet film thicknesses of 0.7 μm, 1.2 μm, and 2.7 μm. (b) The temperature dependence of the Faraday rotation angle for the 2.7-µm-thick Bi:RIG film. The garnet film was heated and cooled in the applied magnetic field after magnetization. The magnetic field was applied in the direction opposite to the initially-magnetized direction. (c) The Faraday rotation angle of initial magnetization, and (d) the Faraday rotation angle of reversed magnetization.
