We studied Nd3-XBiXFe4GaO12 films to obtain perpendicular magnetic anisotropy as well as large Faraday effect. NdBi2Fe4GaO12 (Bi2:NIGG) and Nd0.5Bi2.5Fe4GaO12 (Bi2.5:NIGG) films were obtained on Nd2BiFe4GaO12 (Bi1:NIGG) layer prepared on glass substrates by metal-organic decomposition (MOD) method. Bi2:NIGG and Bi2.5:NIGG films showed large Faraday rotation angles of 7.5 and 10.5 degree/µm, at a wavelength of 520 nm, respectively. Those films have perpendicular magnetic anisotropy with a coercivity of 350 Oe and a saturation magnetic field of 730 Oe.
