A systematic study of the transverse voltage at zero magnetic field in the superconducting state is reported. The effects of warming rate, temperature, applied magnetic field, and electrical current on the transversal resistance (RXY) of polycrystalline superconducting sample are taken into account. At zero magnetic field two peaks are observed in RXY(T) curves which are related to the double superconducting transition in the RXX(T) component. In the superconducting (RXX = zero) and normal states no transverse voltage has been detected at zero magnetic field as expected. The results are discussed within the framework of the motion of Abrikosov and Josephson vortices and anti-vortices. A new scaling relation between transverse and longitudinal components given by RXY ∼ dRXX/dT has been confirmed.
