Growth and Characteristics of YIG, Bi:YIG, TbBi:YIG Single Crystal Thick Films
The single crystalline thick films of Y$_3$Fe$sub$5/O$sub$12/(YIG), Y$_3$Fe$sub$5/O$sub$12/(Bi:YIG), (TbBi)$_3$(FeAlGa)$sub$5/O$sub$12/ (TbBi:YIG) were grown on (GdCa)$_3$(GaMgZr)$sub$5/O$sub$12/ (SGGG) by Liquid Phase Epitaxy (LPE). The change of lattice mismatch, Bi concentration, characteristic of magnetic and surface morphology were investigated in the thick film growth as a function of species and amount of chemical element, while substrate rotation speed, supercooling and growth time were kept constant. It was observed that the lattice constant of garnet single crystalline thick films of TbBi:YIG (12.500 ${AA}$) is closed to the one of the substrate (12.496 ${AA}$). Besides magnetic field of saturation exhibits excellent results (150 Oe).
Key words: Garnet, Bi, TbBi:YIG, LPE, SGGG
