Fig. 5: Results of magneto-optical Kerr rotation angle.

a DFT results of Kerr angle for Fe, LaFeO₃ and La(Fe_0.75D_0.25)O₃ with D = Ni, Cu, and Zn. b DFT results of Kerr rotation angle for La(Fe_0.75D_0.25)O₃ with D = Mo, Pd, and Cd. Experimental Kerr rotation angle of Fe⁸⁸ is also included for comparison. Results here are obtained without Fe substrate.
