Abstract

RuSr2GdCu2O8, in which magnetic order and superconductivity coexist with T-mag>T-c, is a complex material which poses new and important questions to our understanding of the interplay between magnetic and superconducting order. Resistivity, Hall-effect, and thermopower measurements on sintered ceramic RuSr2GdCu2O8 are presented, together with results on a broad range of substituted analogs. The Hall effect and thermopower both show anomalous decreases below T-mag, which may be explained within a simple two-band model by a transition from localized to more itinerant behavior in the RuO2 layer at T-mag.
