Abstract

Two different thermomagnetic transport quantities, the electrothermal conductivity and the Nernst effect are shown to be powerful probes of high-temperature superconductors. In the vortex state below T_c, the electrothermal conductivity is independent of both the magnetic field and the cortex viscosity because it is sensitive only to the properties of the vortex normal cores. Some new data from cuprate superconductors show a surprising, low-field anomaly in the dilute vortex limit. Above T_c in the normal state, it is shown how the Nernst effect is a probe of transport anisotropy around the Fermi surface.
