The fabrication technology of YBCO high Tc superconducting fulms on metallic tapes and their practical applications habe beel studied. The textured crystalline structures, the material and fabrication requirement for thick and long films, favrication technique of various superconducting shape including solenoid, tube, and ring, are incestigated. We analyze the dynamicl coupled behavior of the supercurrent and the magnetic flux using phenomenological theories.
Developments and characterizations of high Tc superconducting device
The aroius TBCO high Tc superconducting devices fabiricated on oxide substrates such as Josephson device, infrared detector, and noise shielder have been developed. Their properties have been measured and analyzed.
In order to understand the measured properties of the developed devices, We analyzed using the numerical simulations of the dynamical superconductiong phenomena which are described by the Josephson array model or time dependent Ginzberg-Landau equation.
