Abstract: Magnetic garnet compositions grown by liquid phase epitaxy have appropriate magnetic properties for use in bubble domain devices - a class of magnetic devices in which information is represented by enclosed domain regions of polarity opposite to that of immediately surrounding material. Critical selection of compositions, all containing mixed rare earth cations, as well as careful choice of processing conditions yield films which are both uniform in composition and dimension, as well as lacking in hillock formation and other surface irregularities.
