Zusammenfassung:The overall objective of this research was to prepare single-crystal films of new and improved ferrite materials. The emphasis was on materials which will be useful in microwave and millimeter-wave signal processing devices. The research was concentrated on two classes of ferrites: the magnetic garnets typified by YIG (Y3Fe5012) and the hexagonal ferrites based on barium hexaferrite (BaFe12019). In addition, some work was done on spinel ferrites including lithium ferrite (Li0.5Fe2.504). Single crystal films of these ferrites were grown on appropriate substrates by the LPE (liquid phase epitaxy) process. (Author)
