Abstract

The intrinsic pinning mechanism of YBa2Cu3O y coated conductors was investigated in terms of the anisotropy of Jc. The dissipation in the intrinsic pinning is mainly due to the double-kink excitation of the pinned vortices in the intermediate temperature region between 70 and 40 K. In this temperature region, the n-value is as small as about 8-10. At low temperature below 20 K, however, n-values become large and Jc is independent of the magnetic field because of the reduction of the double-kink excitation of the vortices.
