Abstract

Using results from previous work on a spin-polaron model of high-

T_{c}

superconductivity, together with a hole-filling mechanism, excellent agreement with experimental data for

T_{c}

in Y-Ba-Cu-O and Pr-Ba-Cu-O alloys and layered structures is obtained without introducing either pair breaking by the Pr ions or pairing interactions between unit cells.
