Anisotropic characteristic lengths in single crystal YBa/sub 2/Cu/sub 3/O/sub 7-delta/

Conference ·
OSTI ID:5132149
In this paper we review the available data on the upper critical field in single crystal samples of YB a/sub 2/Cu/sub 3/O/sub 7-delta/ and extract values for the slope near T/sub c/. We report new measurements of the lower critical field at low temperature from magnetization data on several single crystals with varying strength of flux pinning. We then infer the anisotropy of the Ginzburg-Landau parameter, coherence length, and penetration depth from the measured upper and lower critical field data using London electrodynamics. 8 refs., 3 tabs.
