Аннотация
A giant zero-bias anomaly is observed in the differential conductivity of tunnel junctions based on the La and Y ceramics that do not exhibit superconducting properties. This anomaly is ascribed to the disordering effects responsible for the transition of metal oxides to the normal state.
