    摘要: With the fabrication of a substrate material in the form of alkaline-earth gallate single crystals it has become possible to grow monocrystalline barium hexaferrite layers of high quality. These thin barium hexaferrite layers on the alkaline-earth gallate substrates are extremely suited as magnetic devices because of their very high uniaxial anisotropy and their small line width. Such magnetic devices can be used for passive microwave components, e.g. as resonance isolators or filters in the centimeter wavelength range, or as components in information storage technology, e.g. in magnetic cylindrical domain devices, especially in the field of very small (submicron) cylindrical domains.
