| Abstract: | Low frequency transport measurements are performed on GdSr2RuCu2O8 pellets. The observed current-voltage curves are qualitatively explained in the framework of a simple phenomenological model accounting for coexistence in the sample of ferromagnetism and superconductivity. 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.
