Effects of Self-field and Low Magnetic Fields on the Normal-Superconducting Phase Transition
M. C. Sullivan, D. R. Strachan, T. Frederiksen +2
Researchers have studied the normal-superconducting phase transition in the high- cuprates in a magnetic field (the vortex-glass or Bose-glass transition) and in zero field. O…
Normal-Superconducting Phase Transition Mimicked by Current Noise
M. C. Sullivan, T. Frederiksen, J. M. Repaci +3
As a superconductor goes from the normal state into the superconducting state, the voltage vs. current characteristics at low currents change from linear to non-linear. We show the…
The zero-field superconducting phase transition obscured by finite-size effects in thick films
M. C. Sullivan, D. R. Strachan, T. Frederiksen +3
We report on the normal-superconducting phase transition in thick films in zero magnetic field. We find significant finite-size effects at low curre…
Point contact spectroscopy of the electron-doped cuprate superconductor Pr{2-x}Ce{x}CuO4: The dependence of conductance-voltage spectra on cerium doping, barrier strength and magnetic field
M. M. Qazilbash, Amlan Biswas, Y. Dagan +2
We present conductance-voltage (G-V) data for point contact junctions between a normal metal and the electron doped cuprate superconductor Pr{2-x}Ce{x}CuO4 (PCCO). We observe a zer…
