Measurements of the magnetic properties of conduction electrons

Abstract

We consider various methods and techniques that are used in experimental condensed matter physics for measuring electron magnetization and susceptibility. The list of considered methods for macroscopic measurements includes magnetomechanical, electromagnetic, modulation-type, and thermodynamic methods based on chemical potential variation measurements. We also consider local methods of magnetic measurements based on the spin Hall effect and nitrogen-substituted vacancies (NV centers). Scanning probe magnetometers–microscopes are considered, such as the magnetic resonance force microscope, SQUID microscope, and Hall microscope. The review focuses on the electron spin magnetization measurements in nonmagnetic materials and systems, particularly in low-dimensional electron systems in semiconductors and in nanosystems that have come to the forefront in recent years.
