Description

From the temperature and magnetic-field dependences of the tunneling structures on YBaCuO/Pb thin films structures, interesting results concerning the energy gaps of Pb, YBCuP and possibly proximity-effect influenced other structures are obtained. The additional resonances above the gap can be connected with the existence of localized baglike excitations in the 2-dimensional fermion system of Cu-O planes. The calculated energy changes of the bags by changing the number of the included quasiparticles are in the range of the experimental results for the resonance steps
