During this program we surveyed a number of new substrate and solvent solution systems for epitaxial ferrite growth. the growth of single crystals of two new materials, cobalt gallate and Ta-substituted barium vanadate, was successfully demonstrated. Compositions lattice-matched to the ferrites were demonstrated, and ferrite films were grown on cobalt gallate. Interdiffusion of barium hexaferrite and barium vanadate prevented high-quality hexaferrite film growth on the latter substrate.
