Abstract

RuSr $_2$ GdCu $_2$ O $_8$ , in which magnetic order and superconductivity coexist with $T_{Magnetic}$ $\gg$ $T_c$ , 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 $T_{Magnetic}$ 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 $T_{Magnetic}$ .
