Abstract
A dc torsional magnetometer for use in high magnetic fields is described. It provides several significant advantages over an earlier device, both by its increased sensitivity and better damping, and also, in particular, because its design allows a torque to be introduced electrostatically. This makes it possible to compensate for monotonic background signals, and to provide a ‘‘transfer standard’’ between calibration and operating conditions. An example is given of its use in the study of the de Haas–van Alphen effect in a single-quantum-well two-dimensional electron system.This publication has 4 references indexed in Scilit:
