Abstract
It has been shown analytically and numerically that the effect of magnetic coherence (interference) of levels in L- and V-type transitions, induced by the field of a traveling linearly polarized electromagnetic (EM) wave of arbitrary intensity, can make a significant contribution both to the populations of transition levels (more ~50% than of the field contribution) and to the absorption resonance spectra during frequency and magnetic scanning. Differences in the manifestation of the magnetic coherence effect in level populations for open and closed types of transitions have been identified. It has been established that narrow coherent electromagnetically induced transparency (EIT) resonances are formed in the absorption resonance spectra during magnetic scanning near zero magnetic field. The dependencies of EIT resonance parameters on the characteristics of atomic transitions and EM wave intensity have been investigated. The contribution of the magnetic coherence effect of transition levels to the shape of these resonances has been revealed.
