Abstract
The second-phase project in the development of fundamental technologies of the superconducting industry started in April 1998. The main purpose of this project is the development of coated superconducting tapes, superconducting electronic devices, and superconducting bearing a system, as well as the development of basic material science of high-Tc materials. In the development of coated conductors, 1-2-3 type materials will be used, and high critical current and excellent magnetic field dependence are expected. In the development of electronic devices, the improvement of single magnetic flux quantum device will be undertaken and the integration of these devices on one chip will be tested. In the development of superconducting bulk and superconducting bearings, the bulks of NdBCO, SmBCO, and other materials will be made to obtain a stronger pinning effect and to get a stronger trapped magnetic field: also, the high-quality bearing system is to be improved. The material science of the high-Tc materials is still very important, and it is expected to emerge as “Device Physics and Chemistry” soon.
