| Popis: |
We report measurements of the critical current, differential resistance, and voltage noise below the vortex-lattice melting transition in clean, untwinned YBa2Cu3O7- crystals. The differential resistance at dc current bias much greater than Jc shows a sharp feature at the melting transition accompanied by a rapid drop in the voltage noise, demonstrating that the melting transition is insensitive to the static pinning potential. In the solid phase, the measurements all show a marked change from the low-field, pinned lattice to the high-field vortex-glass contiguous with the tricritical point in this sample. © 1995 The American Physical Society. 52 6211 6214 6211-6214 |
