Using the weakly perturbative spin noise spectroscopy, we study the electron spin relaxation dynamics without explicit excitation. The observed temperature dependence indicates the presence of localized states, which have an increased interaction with the surrounding nuclear spins. Time-resolved spin noise spectroscopy is then applied to study the relaxation dynamics of the optically pumped nuclear spin system.
