Tuned-circuit differential susceptometer for high-pressure and low-temperature studies of small organic crystals - A new way of measuring quantum oscillations

A new technique has been developed to measure the differential susceptibili ty of small samples under pressure using a tuned circuit. The very low heat dissipation in the experiment means that the technique can be transferred easily to a dilution fridge. Our setup provides a simple and versatile way of measuring the de Haas-van Alphen (dHvA) effect under pressure.
