In order to achieve high performance high temperature superconducting energy grids without energy consumption, origins of superconductive degradation induced by introduction of artificial pinning centers (APC's) which can enhance critical current density in a magnetic field are investigated. The vicinal angle dependence of the substrates on the growing mechanism of APC's was examined by using several kinds of vicinal surface substrates. As a result, the bending of one-dimensional APC's began to grow along the step flow of the crystal growth as the vicinal angle increases. These APC's are not suitable to enhance the pinning force against flow of the c-axis oriented vortexes. During the research period, fabrication process of coated superconductors is examined to decrease firing temperature which induces inter-diffusion of constituent atoms. In addition, I also studied to examine in detail the upper critical magnetic field of the iron-based superconducting film.

为了实现无能耗的高性能高温超导能量网，研究了引入人工钉扎中心(APC‘s)以提高磁场中的临界电流密度而导致超导退化的根源。用几种邻近表面的基质考察了基质的邻角对APC生长机理的影响。结果表明，随着邻近角的增大，一维APC的弯曲开始沿着晶体生长的台阶流生长。这些APC不适合提高c轴取向涡流的钉扎力。在研究期间，研究了涂层超导体的制备工艺，以降低引起组分原子互扩散的烧成温度。此外，还对铁基超导薄膜的上临界磁场进行了详细的研究。
