| Outline of Final Research Achievements |
Using a metal organic decomposition method with electron beam irradiation, we have succeeded in fabricating high-quality yttrium-iron garnet micropatterns without a dry-etching process. We found that the magnitude of the nonreciprocity of magnetostatic surface waves in a permalloy medium is controlled by changing a distance between a permalloy medium and an excitation antenna. We succeeded in improving the properties of Ge thin-film transistors fabricated by a gold-induced crystallization method by post-annealing of 400C.
