  • Abstract
    Single crystal films having the nominal composition Y\\min{3-x}\\max {3+}Ca\\min{x}\\max {2+}Ge\\min{y}\\max {4+}Fe\\min{5-x}\\max {3+}Fe\\min{x-y}\\max {4+}O\\min{12}\\max {2-} have been grown by liquid phase epitaxy and analyzed by magnetic resonance at room temperature. A large magnetic damping, a fairly high cubic anisotropy term K2, and an electrical p-conductivity of the order of 10-5Ω-1cm-1, all suppressible by a chemicalin the crystal. An increase of the uniaxial anisotropy is also observed in the reduced specimens. This effect produces a drastic variation of the domain pattern which changes from narrow parallel domains (asgrown film) to mazelike stripe domains (reduced film).
