Abstract:

The effect of the increase of the critical temperature Tc by the irradiation of the Y123 samples with small doses of fast neutrons has been investigated by the temperature dependence of resistance and EPR studies. The results indicated that Tc and EPR signals of all specimens are increased with increasing irradiation fluences. These results are explained in terms of redistribution of oxygen, which promotes charge ordering in the superconducting CuO2 planes. © 1999 Elsevier Science B.V. All rights reserved.
