This work reports longitudinal (RXX) and transverse (RXY) resistance as a function of the temperature measured at low magnetic fields for a Y0.55Pr0.45Ba2Cu3O7-d polycrystalline sample. It is observed nonzero transverse voltage at zero external magnetic below superconducting transition and above no such voltage was detected. Comparing RXX (T) and RXY (T) curves it was possible to observe a correlation between Hall resistance and double resistive superconducting transition. Magneto-resistance RXX(H) measurements showed that the dissipation is dominated by weak coupling between superconducting clusters. I-V and R(T) curves of both components suggest that the positive Hall voltage at superconducting state must be related to quasiparticle currents.
