In this study, we calculated the repulsive force of magnetic levitation for superconductive-assisted machining (SUAM) using the finite element method. Conventionally, SUAM utilizes bulk superconductors; here, we propose a magnetic levitation tool usi

When the critical current density J c for a superconductor is constant, the critical current I c increases in proportion to the superconducting cross-sectional area. However, in the case of a superconducting coated conductor, when the thickness of th

The purpose of this study is to generate a highly stable DC current by using a superconducting transformer. For the first trial stage, a 100 A class superconducting transformer was designed and fabricated for operation at the temperature of liquid ni

It was shown that the current-carrying capacity of a superconducting DC power cable could be dramatically increased using the longitudinal magnetic field effect. That is, the force-free structure was assumed for the conductor in the cable to use a si

The effect of flux creep is noticeable on the critical current density, Jc, of oxide superconductors especially at high temperatures. One of the remarkable features of the phenomenon is that the irreversibility line, i.e., the boundary of zero and no

The condensation energy of Bi‐2212 superconductor in various doped states was evaluated from the flux pinning strength of columnar defects. For the purpose the collective flux creep theory was used to estimate the virtual critical current density i
