Tunnel junctions on 1:2:4 YBaCuO single crystal

Abstract:

We have studied the 1:2:4 phase of the YBaCuO compound by means of tunneling spectroscopy on single crystal based junctions. The crystals, with Tc≈80 K, have been chemically etched before the deposition of the counterelectrode in form of a thin film through a metallic mask. We have compared the tunneling spectra to those obtained on the Y123 system. The features at ±20 mV of the 1:2:3 phase are still observed in the 1:2:4 phase, while the low bias features at ±5 mV are not present in the tunn...
