Low frequency transport measurements have been performed on GdSr2RuCu2O8 pellets. The current-voltage curves measured show an irreversible behavior in whole range of temperature explored. From these curve a Curie temperature TcM=133 K and a superconducting critical temperature TcS = 14 K, with an onset temperature TcO=33 K, have been deduced. A simple phenomenological model assuming a non-linear inductance in series with a resistance has been proposed to explain experimental current-voltage curves. Within this model, the temperature dependence of some physical quantities has been also investigated.

Abstract
Low frequency transport measurements have been performed on GdSr2RuCu2O8 pellets. The current-voltage curves measured show an irreversible behavior in whole range of temperature explored. From these curve a Curie temperature TcM=133 K and a superconducting critical temperature TcS = 14 K, with an onset temperature TcO=33 K, have been deduced. A simple phenomenological model assuming a non-linear inductance in series with a resistance has been proposed to explain experimental current-voltage curves. Within this model, the temperature dependence of some physical quantities has been also investigated.File in questo prodotto:
