Description
Transitions in a system of neutrinos with vacuum mixing and magnetic moments, propagating in matter and transverse magnetic field, are considered. It is shown that in the realistic case of magnetic field direction varying along the neutrino path qualitatively new phenomena become possible: permutation of neutrino conversion resonances, appearance of resonances in the neutrino-antineutrino ($ν_{lL}\leftrightarrow\barν_{lR}$) transition channels, neutrino-antineutrino resonant conversion, large amplitude $ν_{lL}\leftrightarrow\barν_{lR}$ oscillations, merging of different resonances (triple resonances). Possible phenomenological implications of these effects are briefly discussed.
