Abstract

Low frequency transport measurements are performed on GdSr $_2$ RuCu $_2$ O $_8$ pellets. The observed current-voltage curves are qualitatively explained in the framework of a simple phenomenological model accounting for coexistence of ferromagnetism and superconductivity in the sample. A Curie temperature $T_{cM}$ =133 K and a superconducting critical temperature $T_{cS}$ =18 K, with an onset temperature $T_{cO}$ =33 K, are extracted from the analysis of the current-voltage curves.
