G. Karchava et al., The influence of small doses of fast neutron irradiation on the critical temperature and EPR spectra of YBa2Cu3O7-delta high temperature superconductors, PHYSICA C, 318, 1999, pp. 561-564
The effect of the increase of the critical temperature T-c by the irradiati
on of the Y123 samples with small doses of fast neutrons has been investiga
ted by the temperature dependence of resistance and EPR studies. The result
s indicated that T-c and EPR signals of all specimens are increased with in
creasing irradiation fluences. These results are explained in terms of redi
stribution of oxygen, which promotes charge ordering in the superconducting
CuO2 planes. (C) 1999 Elsevier Science B.V. All rights reserved.
