Description

This paper presents planar and edge-type tunnel junctions YBa2Cu3Ox-metal (Pb,Pt,In) based on epitaxial Y-Ba-Cu-O films. Features of conductance characteristics of these junctions, mainly conductance zero bias anomalies, have been considered. We have observed the difference between the Rd(V) dependences for two types of the contacts at low bias voltages V approx-lt 5 mV. This difference probably linked with an anisotropy of the states density N (ε) in near-contact region of YBa2Cu3Ox. Existence of the correlation in the temperature dependences of the states density of YBa2Cu3Ox along the Cu-O planes and perpendicularly to them have been observed
