Figure 1: The Nernst effect occurs when a material is exposed to a temperature gradient and a magnetic field. Mobile charges (referred to as quasiparticles) will tend to move from the warm to the cold side (x direction), but this motion will induce a force coming from the magnetic field (z direction). Charge collection in the y direction results in an electric field, constituting the quasiparticle Nernst signal.
