| Abstract | |
This work reports longitudinal (R-XX) and transverse (R-XY) resistance as a function of temperature measured at low magnetic fields for Y0.55Pr0.45Ba2Cu3O7-delta polycrystalline sample. It is observed non-zero transverse resistance at zero applied magnetic field below superconducting transition. The comparison between R-XX (T) and R-XY (T) curves demonstrate unambiguously that the transverse resistance is related to the double resistive superconducting transition in granular superconductors. I-V curves indicate that the transport properties of the investigated sample are in agreement with the predictions of the two-fluid model. (AU) | |
