Possibility of a s-wave pairing in heavily Zn-doped YBa₂Cu₃O₇₋δ based on magnetic field effect on Andreev reflection spectra
When the dx₂₋y₂ -wave pairing is suppressed by Zn-doping in YBa₂Cu₃O₇₋δ some of the Andreev reflection spectra were found to be similar to the s-wave spectra of conventional superconductors. The energy gap is rather reproducible (2.3–3.0 meV). It is suppressed by low magnetic field (HcPC = 120–270...
