The generalized theory of the Hanle effect is developed for the case of propagation quantum beats. Time-integrated quantum beats of two polariton wave packets with the same group velocities and polarizations belonging to two different Zeeman components in Voigt geometry of the quadrupole-active ortho-exciton Γ+5 level in Cu2O crys gives rise to the propagation Hanle effect. It is characterized by a quasiresonant dependence of the emitted light intensity on the magnetic field strength, as well as by a supplementary periodic dependence with the period inverse proportional to the sample thickness. The developed theory with the account of the effective propagation way explains recent experimental results published by Kono and Nagasawa. © Society of Photo-Optical Instrumentation Engineers. |
