Abstract

PURPOSE: To produce high quality bubble element by unilizing the heat treatment characteristics of CaGe garnet epitaxial film to selectively change the uniaxial magnetic anisotropic energy (Ku) of bulb material.
CONSTITUTION: Chemically stable oxide such as SiO2lAl2O3 etc. or metal with high melting point such as Si or Au etc. is evaporated to stay on CaGe material with heat treatment atmospheric reliability of ku except the part where Ku is to be changed. When heat treated in a fixed temperature and a fixed oxygen pressure, the part not covered with vapor-attached film is exposed to oxygen atmosphere to decrease Ku depending on the oxygen pressure, heat treatment temperature, heat treatment period. Thus, the Ku of material can selectively be changed.
