Abstract

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).

Y$_3$Fe$_{5}$O$_{12}$(YIG), $Y_3$Fe$_{5}$O$_{12}$(Bi:YIG), TbBi:YIG를 (GdCa)$_3$(GaMgZr)$_{5}$O$_{12}$ (SGGG)기판 위에 Liquid Phase Epitaxy (LPE)법으로 단결정 후막을 성장시켰다. 기판회전속도, 과냉도, 성장시간을 고정하여 치환되는 원소의 종류와 양에 따라 가네트 단결정의 격자상수, Bi 치환양, 표면형상, 자기적 특성을 조사하였다. TbBi:YIG 조성의 경우 격자상수는 12.500 $\AA$으로 기판의 격자상수인 12.496 $\AA$에 근접하게 나타났으며, 포화자계는 150 Oe로 향상된 결과가 나타났다.
