Abstract
An overview of the elaboration of V. G. Bagrov’s remarkable results on the emission of a special type of electromagnetic radiation by a particle moving in a magnetic field, referred to as the spin light, is given. It is common knowledge that synchrotron radiation of an electron, in addition to the electron-charge contribution, also contains that of a spin magnetic moment, which is exactly the spin light. V. G. Bagrov was among the founders of the spin light theory; he investigated this kind of radiation for a neutral particle—a neutron in a magnetic field, in which case the emission represents a pure spin light. By an analogy, the problem of spin light radiation can be considered for another neutral particle—a neutrino. In this article we present the basic theoretical results and an application of the Spin Light of Neutrino phenomenon, which occurs when a Dirac neutrino moves in matter.
期刊介绍:
Russian Physics Journal covers the broad spectrum of specialized research in applied physics, with emphasis on work with practical applications in solid-state physics, optics, and magnetism. Particularly interesting results are reported in connection with: electroluminescence and crystal phospors; semiconductors; phase transformations in solids; superconductivity; properties of thin films; and magnetomechanical phenomena.
