A Trapped Field of 17.6 T in Melt-Processed, Bulk Gd-Ba-Cu-O Reinforced with Shrink-Fit Steel
John H. Durrell, Anthony R. Dennis, Jan Jaroszynski +8
The ability of large grain, REBaCuO [(RE)BCO; RE = rare earth] bulk superconductors to trap magnetic field is determined by their critical current. With high tr…
A Trapped Field of >3T in Bulk MgB2 Fabricated by Uniaxial Hot Pressing
J. H. Durrell, C. E. J. Dancer, A. Dennis +7
A trapped field of over 3 T has been measured at 17.5 K in a magnetised stack of two disc-shaped bulk MgB2 superconductors of diameter 25 mm and thickness 5.4 mm. The bulk MgB2 sam…
Theory and experiment testing flux-line-cutting physics
John R. Clem, Marcus Weigand, J. H. Durrell +1
We discuss predictions of five proposed theories for the critical state of type-II superconductors accounting for both flux cutting and flux transport (depinning). The theories pre…
Remagnetization of bulk high-temperature superconductors subjected to crossed and rotating magnetic fields
P Vanderbemden, Z Hong, T A Coombs +4
Bulk melt-processed Y-Ba-Cu-O (YBCO) has significant potential for a variety of high field permanent magnet-like applications, such as the rotor of a brushless motor. When used in…
Behavior of bulk high-temperature superconductors of finite thickness subjected to crossed magnetic fields
Ph. Vanderbemden, Z. Hong, T. A. Coombs +7
Crossed magnetic field effects on bulk high-temperature superconductors have been studied both experimentally and numerically. The sample geometry investigated involves finite-size…
Thermal Instability and Current-Voltage Scaling in Superconducting Fault Current Limiters
Bernhard Zeimetz, K Tadinada, D E Eves +3
We have developed a computer model for the simulation of resistive superconducting fault current limiters in three dimensions. The program calculates the electromagnetic and therma…
