Magnetic Susceptibility Measurements in HgTe Quantum Wells in a Perpendicular Magnetic Field

The magnetic susceptibility of two-dimensional systems in the limit of low fields can hardly be detected by magnetometric measurements because it is difficult to separate the contributions from the substrate and two-dimensional gas for the magnetization not oscillating with the field. The derivative...

Zusammenfassung:	The magnetic susceptibility of two-dimensional systems in the limit of low fields can hardly be detected by magnetometric measurements because it is difficult to separate the contributions from the substrate and two-dimensional gas for the magnetization not oscillating with the field. The derivative of the magnetization with respect to the carrier density in two-dimensional systems in narrow (thickness
