| Research Abstract |
In order to obtain high-performance superconducting wire made of RE based superconductor, we investigated low cost thin film fabrication process and rapid screening of magnetic flux pinning materials. At present, an excimer laser is employed as the laser source of the pulsed laser deposition (PLD) method. In this study, we used Nd:YAG laser for a fabrication of RE based superconducting films, because the Nd:YAG laser is environmentally safe and economical due to the low initial and running cost and the absence of poisonous or hazardous gases. As a result, we clarified that the RE based films which were prepared by Nd:YAG-PLD method exhibited good superconducting properties identical to the films obtained by usual excimer-PLD method. We also showed that combinatorial-PLD method which is based on combinatorial chemistry is useful for exploration of new pinning materials, and we searched new pinning materials.
