Research for High-Performance Superconducting Wire:
Since superconducting materials exhibit zero electrical resistance and expulsion of magnetic fields, they are intensively studied for the application to non-loss electric lines and magnetic levitation train, and so on. 
In order to obtain superconducting materials with higher performance, e.g., higher critical current, higher critical temperature, and so forth, we are studying the optimal material process of these materials. In particular, our attention is focused on artificial pinning center and its distribution within the material, which effectively enhances critical current when superconductors are used in a magnetic field.
