PREPARATION OF GIANT MAGNETOSTRICTIVE THIN FILM FOR OPTICAL SCANNER

摘要

The optical scanning device, which was consisted of TbFe_(1.7) thin film, Silicon wafer mirror and polyimide substrate, was studied. It was found that the device showed linearity and reproducibility in range of magnetic field from 0 kOe to 5 kOe. The scanning area was also enlarged monotonously with increasing the magnetic field. Therefore, the optical scanning device could be developed for practical use.
