  Neutrino-atom scattering provides a sensitive tool for probing nonstandard
interactions of massive neutrinos in laboratory measurements. The ionization
channel of this collision process plays an important role in experiments
searching for neutrino magnetic moments. We discuss some theoretical aspects of
atomic ionization by massive neutrinos. We also outline possible manifestations
of neutrino electromagnetic properties in coherent elastic neutrino-nucleus
scattering.
