We present a theory of time-resolved Faraday rotation for semimagnetic quantum well structures in the Voigt conΓΏguration. The nonlinear part of the Faraday rotation signal is expressed as probing the carrier spin populations requiring an o -resonant probe frequency. Our computed results conΓΏrm exper
## Abstract Continuous representations of the dynamical $SU(2)$ group, and the corresponding generalized coherent states, are used to conjugate dynamics of a system of quantum spins to that of a classical Hamiltonian system. Stability of the Hamiltonian system obtained are studied, using linear sta
