Abstract

Using a new, highly sensitive, torsional magnetometer technique we have observed the de Haas-van Alphen Effect in GaAs/(AlGa)As two-dimensional electron systems. The results for a superlattice of 172 layers are quantitatively compared to theory taking account of finite Landau level width as well as known sample inhomogeneities. In addition, this device is being employed to study the Zero Resistance State of the 2-D electron system via eddy currents generated by small field changes.
