Abstract

Birefringence effect can be used as a tool for astrophysical plasma study. Group delay was discovered between two magnetoionic modes and spectrally confirmed for quasiperiodic narrow band millisecond pulsation. It was found from the cross delays and autodelays that X and O modes were originated at the same source, therefore the radiation was weakly polarized. By these findings the emission mechanism of the pulsations to a nonlinear plasma mechanism operating at the second harmonics was specified. Using the theory of nonlinear plasma mechanism physical parameters of the solar corona were determined.
