| Research Abstract |
We present a method for the growth of oxide single crystal thin films on an amorphous substrate. At the first, we investigated growth of a cerium substituted YIG (Ce:YIG) single crystal film on SiO2 substrate. This method is consisted of two steps. The first step was the deposition of an amorphous film of CeY2Fe5O12 on a SiO2 substrate by RF-magnetron sputtering. The second step was crystallizing the film by raising its temperature to around 600 ?C in a vacuum or in argon (Ar) gas. A single crystal film of Ce:YIG was obtained after this thermal treatment. For the thermal treatment process to work, a small chip of GGG plate was placed on top of the film. Before contact with each other, the chip, the surfaces of the chip, and amorphous film were refreshed by Ar plasma. The surface refreshing process was decisive for single crystal growth.
