de Haas–van Alphen measurements on CeRhIn5 under pressure

Abstract Measurements of the de Haas–van Alphen effect have been carried out on the heavy fermion anti-ferromagnet CeRhIn5 at temperatures between 25 and 500 mK under pressure. We present some preliminary results of our measurements to track the evolution of the Fermi surface as the pressure induced superconducting transition is approached.
