  The main goal of the paper is to give a short review on neutrino
electromagnetic properties. In the introductory part of the paper a summary on
what we really know about neutrinos is given: we discuss the basics of neutrino
mass and mixing as well as the phenomenology of neutrino oscillations. This is
important for the following discussion on neutrino electromagnetic properties
that starts with a derivation of the neutrino electromagnetic vertex function
in the most general form, that follows from the requirement of Lorentz
invariance, for both the Dirac and Majorana cases. Then, the problem of the
neutrino form factors definition and calculation within gauge models is
considered. In particular, we discuss the neutrino electric charge form factor
and charge radius, dipole magnetic and electric and anapole form factors.
Available experimental constraints on neutrino electromagnetic properties are
also discussed, and the recently obtained experimental limits on neutrino
magnetic moments are reviewed. The most important neutrino electromagnetic
processes involving a direct neutrino coupling with photons (such as neutrino
radiative decay, neutrino Cherenkov radiation, spin light of neutrino and
plasmon decay into neutrino-antineutrino pair in media) and neutrino resonant
spin-flavor precession in a magnetic field are discussed at the end of the
paper.
