Abstract
Measurements of the superconducting critical temperature are reported for the () system as a function of x and y. The vs c curves at fixed values of x can be resolved into two contributions: (1) the counteracting effects of generation and filling of holes in the sheets by and ions, respectively, and (2) the depairing of superconducting electrons via exchange scattering of the mobile holes in the sheets by the Pr magnetic moments.
