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…
The Normal State Resistivity of Grain Boundaries in YBa2Cu3O7-delta
J. H. T. Ransley, S. H. Mennema, K. G. Sandeman +6
Using an optimized bridge geometry we have been able to make accurate measurements of the properties of YBa2Cu3O7-delta grain boundaries above Tc. The results show a strong depende…
Effect of varying material anisotropy on critical current anistropy in vicinal YBaCuO thin films
J. H. Durrell, R. Roessler, M. P. Delamare +3
The high cuprate superconductors are noted for their anisotropic layered structure, certain of these materials indeed tend toward the limit of a Lawrence-Doniach supercondu…
Flux line lattice structure and behaviour in anti-phase boundary free vicinal YBa2Cu3O7-d thin films
J. H. Durrell, S. H. Mennema, Ch. Jooss +4
Field angle dependent critical current, magneto-optical microscopy, and high resolution electron microscopy studies have been performed on YBa2Cu3O7-d thin films grown on mis-cut s…
Application of Percolation Theory to Current Transfer in Granular Superconductors
B. Zeimetz, B. A. Glowacki, J. E. Evetts
We investigate the description of current transfer in polycrystalline superconductors by percolation theory and its limitations. Various computer models that have been proposed are…
Vortex Channeling and the V-I Characteristic of YBa2Cu3O7 Low Angle Grain Boundaries
M. J. Hogg, F. Kahlmann, E. J. Tarte +2
We have performed V-I measurements on a thin film YBa2Cu3O7 4^o [001] tilt low angle grain boundary over an extensive range of temperature and field, verifying the presence of a li…
