Abstract
The theory of absorption and emission of light by free electrons in ferromagnetic semiconductors (FMSC) is considered. General expressions are obtained for an absorption coefficient and for intensity of light emission by free electrons in the FMSC in case of the presence of hot electrons, when electron–bimagnon scattering is prevalent. At this, the dependence on the electron concentration and temperature is taken into account. Classical and quantum cases are considered. It is shown that the intensity of spontaneous radiation does not depend on the frequency of light in the classical frequency range, but it falls exponentially in the quantum region of frequencies.
