Title: Oxide garnet single crystal and manufacture thereof
Inventor: RIYUUOU TOSHIHIKO
IPC: C30B33/10
Filed: 1988-09-30
Abstract: PURPOSE:To remove the generation of a pit of an epitaxial film while making the thickness uniform and reducing the magnetic resonnance half value width DELTAH to less than 2.00e by removing a transition phase on the surface of an oxide garnet single crystal grown up on a substrate by a liquid phase epitaxial method. CONSTITUTION:A transition phase on the surface of an oxide garnet single crystal film grown up on a substrate by a liquid phase epitaxial method is removed. That is, as to bringing up of the oxide garnet single crystal, the substrate consisting of a rare earth metal, garium and garnet is dipped into the molten liquid of the oxide garnet single crystal in order to bring up the oxide garnet single crystal into a film shape by a known liquid phase epitaxial method. The film obtained in this way is eteched or polished by mineral acid such as phosphoric acid, sulphuric acid, nitric acid and hydrofluoric acid, or these are combined. Thereby, this film has no transition phase on the surface while having little unevenness of the thickness and a defect on the film surface is gone further making the magnetic resonnance half value width DELTAH less than 2.00e.
