Disorder Driven Localization in Charge Neutrally Doped 123 Superconductors
2006 (English)In: Low Temperature Physics / [ed] Takano, Y; Hershfield, SP; Hirschfeld, PJ; Goldman, AM, 2006, Vol. 850, 439-440 p.Conference paper (Refereed)
Charge neutral dopings with equal amounts of CaTh or CaPr on rare earth site in Nd-123 have been investigated by studies of the normal state electrical resistivity, p, the Seebeck coefficient S, and the Hall coefficient R-H. In spite of comparable rates of depression of the superconducting T, significant differences are observed in the doping concentration dependence of p, S, and RH between the two dopings. These results are discussed in terms of disorder induced localization.
