  Abstract:  Magnetoresistivity and Hall effect on the samples of Ru1-xSbxSr2 Sm1.5Ce0.5Cu2O10-d were investigated in the temperature range 4-300 K with a magnetic field up to 9 Tesla . Superconducting transition temperature decreases with increases content of Sb, due to a distortion of RuO6 octahedral, which is responsible of the increase in hole localization, reflected by Hall concentration, too. The inhomogeneous granular structure is shown by the intragranular, Tco, and intergranular ,Tcg, transition temperatures. Hall effect anomalous decreases below Tmagnetic can be explained within a simple two-band model by a transition from localized to more itinerant behavior in the RuO2 layer at Tmagnetic .
