[en] We report the electrical resistivity and thermoelectric power of polycrystalline Pb-doped Pi 2:2:2:3 superconductors. In particular the mixed-state properties are investigated by measuring the longitudinal and transverse (Nernst) thermoelectric power. For the first time we show the presence of hysteresis in a high magnetic field for the Nernst effect. We discuss the variation with magnetic field in the properties with respect to the zero-field case and show the power-law behaviour with exponents depending on the transport quantity. We extract 'derived properties' such as the effective mass, the transport entropy, the Ginzburg-Landau parameter, the thermal Hall angle and the activation energy and compare them with previous data on related systems.
