Magneto-Optic Properties of Ultrathin Nanocrystalline Ferrite Garnet Films in the 8K to 300K Temperature Interval

Figure 5

Spectral dependency of the MCD signal (blue diamond) measured in a 10.3 nm-thick iron garnet film of nominal composition Bi₂Dy₁Fe₄Ga₁O₁₂ grown on a gadolinium gallium garnet (GGG) substrate. Films of the same thickness and composition grown on glass substrates did not show (pink square) any magneto-optic activity. The dichroghraph sensitivity scale used was 5 × 10⁻⁶.
