Influence of substitutions on the magnetic anisotropy of Gd-containing magnetooptic iron garnet films

The properties of magnetooptical films of the system (Bi,Gd,Ln)3(Fe,M)5O12, where Ln = Lu or La and M = Ga or Al, grown by liquid-phase epitaxy on Nd3Ga3O12 substrates oriented along (100), along (110), and close to (111), are investigated by x-ray and ferromagnetic resonance methods.
