Magnetoresistance of Junctions made of Underdoped YBCO Separated by a Ga-doped YBCO Barrier
L. Shkedy, G. Koren, E. Polturak
We report magnetoresistance measurements of ramp type superconductor-normal-superconductor (SNS) junctions. The junctions consist of underdoped (YBCO) electrodes…

Observation of McMillan-Rowell like oscillations in underdoped YBCO junctions oriented along the node of the d-wave order parameter
L. Shkedy, P. Aronov, G. Koren +1
Dynamic resistance spectra of ramp junctions made of underdoped YBCO electrodes and Ga-doped YBCO barrier are reported. Series of equidistant peaks were observed in these spectra i…

Observation of a common symmetry for the pseudogap and the superconducting order parameter near the surface of underdoped YBCO
G. Koren, L. Shkedy, E. Polturak
Measurements of the angular dependence of conductance spectra in the a-b plane of underdoped YBCO junctions are reported. At zero magnetic field the superconducting gap shows a |d+…
