Abstract
The superconducting density of states for the cuprates, particularly f or the Y-Ba-Cu-O compound, has been evaluated, add its dependence on t emperature and the oxygen content has been analyzed. The analysis is b ased on the two-gap model. Moreover, the magnetic scattering and corre sponding pair-breaking effect, correlated with the oxygen depletion, i s taken into account as a key factor. The temperature dependencies of the energy gaps are calculated. Intensive magnetic scattering leads to gaplessness. The calculation allows us to describe various experiment al data.
