Abstract

RuSr $_{2}$ GdCu $_{2}$ O $_{8}$ , in which magnetic order and superconductivity coexist with $T_{M a g n e t i c}$ $≫$ $T_{c}$ , is a complex material which poses new and important questions to our understanding of the interplay between magnetic and superconducting (SC) order. Resistivity, Hall effect and thermopower measurements on sintered ceramic RuSr $_{2}$ GdCu $_{2}$ O $_{8}$ are presented, together with results on a broad range of substituted analogues. The Hall effect and thermopower both show anomalous decreases below $T_{M a g n e t i c}$ which may be explained within a simple two-band model by a transition from localized to more itinerant behavior in the RuO $_{2}$ layer at $T_{M a g n e t i c}$ .
