Nonequilibrium Magnetization of a Two-Dimensional Electron Gas in a Static Magnetic Field
D. R. Faulhaber, H. W. Jiang
Using a sensitive DC torque magnetometer we measure the orbital magnetization by sweeping the density at fixed magnetic fields on GaAs-AlGaAs heterostructures. At low temperatures…

Multiple Phases with the Same Quantized Hall Conductance in a Two-Subband System
X. C. Zhang, D. R. Faulhaber, H. W. Jiang
In a GaAs/AlGaAs two-dimensional electron system with two occupied subbands, the experimentally determined phase diagram in the density-magnetic field plane exhibits rich topologic…

Orbital Magnetization Measurement of the Quantum Hall to Insulator Transition
D. R. Faulhaber, H. W. Jiang
We present a magnetization measurement probing the transition from a quantum Hall to insulating (QH-I) state for a two-dimensional electron gas in a disordered GaAs/AlGaAs heterost…
