ABSTRACT

Using the PbO-B2O3-Bi2O3 flux system, (TbBi)3(FeAlGa)5O12 (TbIG), (EuBi)3(FeAlGa)5O12 (EuIG) and (EuTbBi)3(FeAlGa)5O12 (EuTbIG) films were grown on (GdCa)3(GaMgZr)5O12 (SGGG) substrates by the liquid phase epitaxy (LPE). The saturation magnetization of the grown TbIG, EuIG and EuTbIG films was about 150, 950 and 125 Oe, respectively. The TbIG films resulted in the single magnetic domain while the EuIG and EuTbIG films were observed to be the multi magnetic domains by magnetic force microscope (MFM).
