de Haas van Alphen effect in heavy fermion compounds—effective mass and non-Fermi-liquid behaviour

One reason the de Haas van Alphen (dHvA) effect plays a central role in heavy fermion physics is that the temperature dependence of quantum oscillations can be used to measure effective masses on a Fermi surface specific basis. We present a simple picture of the physics behind this temperature dependence, and discuss the observation of non-Fermi-liquid properties at low millikelvin temperatures via the dHvA effect.
