Zusammenfassung:	The object of this project is to establish a reliable supply of high quality magnetic bubble materials to support the device work of various Department of Defense agencies. This work encompasses bulk, non-magnetic garnet crystal growth (for use as substrates), substrate polishing and preparation, liquid phase epitaxial growth of high performance magnetic garnet film compositions, chemical vapor deposition of Ga-YIG films, and the investigation of arc-plasma spraying as a technique for preparing magnetic bubble garnet films. Characterization data are given for materials delivered during this phase.
