Surface magnetostatic wave element for magnetic garnet single crystal film and a method of manufacturing the same

摘要

PURPOSE: To provide a magnetic garnet single-crystal film for MSSW element and its production method in which the difference of lattice constant against that of a base substrate generates small transition and its crystallization is high even when a film is thick. ;CONSTITUTION: In a magnetic garnet single-crystal film that is grown through a liquid epitaxial growth on a nonmagnetic garnet single-crystal substrate having a different lattice constant, the film is formed on the nonmagnetic garnet single- crystal substrate by means of an intermediate layer whose crystallization is low in comparison with the magnetic garnet single-crystal film.;COPYRIGHT: (C)1995,JPO
