New coherent transient effects formed due to double inhomogeneity, i.e. inhomogeneity in the main precession frequency (Larmor inhomogeneous broadening) and of the rf amplitude expressed in frequency units (Rabi inhomogeneous broadening), in˚uencing the nuclear spin- system dynamics during rf pulse excitation, have been predicted and investigated by use of the method of concatenation of perturbation factors (CPF) in statistical tensors (ST) formalism. Multiple pulse excitation under double inhomogeneity is examined when the repetition period of a pulse sequence is shorter than T1.

Nuclear Spin System

The behavior of the electron spin relaxation time in bulk GaAs layers doped with Mn was studied experimentally. We investigated the dependence of the degree of circular polarization of photoluminescence in transverse and longitudinal magnetic fields. An increase in the relaxation time of the electron spin is found from 25 ns at low pumping power to 400 ns at the threshold pumping power. The effect of resonant cooling of the nuclear spin system by optically oriented electron spins is demonstrated.
