| Research Abstract |
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.
