Cyclotron resonance will be treated in this chapter. The most direct probe of the Fermi surface can be made by observing the cyclotron resonance. A magnetic field is applied to a pure sample at liquid helium temperatures. The sign of the charge carrier can be determined by using the circularly polarized lasers. The data are analyzed in terms of Shockley’s formula or its simplified version. Most often the effective masses for a conductor are determined directly after simple analyses.
