      Tunneling in Pb-YBCO junctions: Determining the symmetry of the pairing state 

      Wollman, D. A.; Harlingen, D. J. Van; Giapintzakis, John; Ginsberg, D. M. (1995)
      We report on our efforts to understand the origin of supercurrent observed in c-axis tunnel junctions on YBCO [Sun A. G. et al., Phys. Rev. Lett. 72, 2267 (1994).] by studying the phase coherence of a-axis/c-axis and ...

      Vortex dynamics below the flux-lattice melting transition in YBa2Cu3O7- 

      Safar, H.; Gammel, P. L.; Huse, D. A.; Alers, G. B.; Bishop, D. J.; Lee, W. C.; Giapintzakis, John; Ginsberg, D. M. (1995)
      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 ...

      Vortex-motion-induced voltage noise in YBa2Cu3O7- single crystals 

      D'Anna, G.; Gammel, P. L.; Safar, H.; Alers, G. B.; Bishop, D. J.; Giapintzakis, John; Ginsberg, D. M. (1995)
      We have investigated vortex motion below the quasistatic melting transition in a detwinned YBa2Cu3O7- single crystal by measuring the differential resistance and the voltage noise. With the magnetic field parallel to the ...
