| Outline of Final Research Achievements |
Imprinting method for fabricating large-area and high aspect ratio pattern was established for Pd-based metallic glass (MG) with high formability and for Gd-based MG with low formability. Sufficient depth of imprinting can be obtained even under the isothermal heating condition at supercooled liquid region for Pd-based MG, while the high-rate isochronal heating condition above crystallization temperature was needed for Gd-based MG. By using imprinting with optimized conditions, we have successfully prepared gratings which are applicable for X-ray and neutron Talbot-Lau interferometer.
