After a brief history of two known types of neutrino mixing and oscillations,

including neutrino spin and spin-flavour oscillations in the transversal

magnetic field, we perform systematic study of a new phenomenon of neutrino

spin and spin-flavour oscillations engendered by the transversal matter

currents on the bases of the developed quantum treatment of the phenomenon.

Possibilities for the resonance amplification of these new types of

oscillations by the longitudinal matter currents and longitudinal magnetic

fields are analyzed. We also consider modifications of the oscillation

probabilities due to possible arbitrary orientation of the magnetic field

vector ${bf B}$ and the matter velocity ${bf v}$.
