Abstract
The existence of anomalous magnetic dipole moments for neutrinos can a ffect neutrino oscillations in the early Universe through previously i gnored refractive effects. Using the real-time approach of finite-temp erature field theory, we have calculated the effective potential for n eutrinos due to their magnetic moments and compared it to the standard model value, in view of the astrophysical and laboratory constraints.
