The programs objective is to improve the compatibility between substrates and films of epitaxially grown magnetic bubble domain materials. The introductory section of this report contains a discussion of the means by which the requirements for the existence of cylindrical magnetic domains may be met in epitaxial films grown by chemical vapor deposition. The experimental section deals with substrate crystal growth and wafer preparation chemical vapor deposition and heat treatment of epitaxial films. Techniques for characterizing magnetic bubble domain films are reviewed and properties of gallium-substituted erbium iron garnet films are discussed. Preparation and properties of polycrystalline ceramic samples of substituted ytterbium iron garnet are presented. Author
