Spin inertia measurements are a novel experimental tool to study long-timespin relaxation processes in semiconductor nanostructures. We develop a theoryof the spin inertia effect for resident electrons and holes localized inquantum dots. We consider the spin orientation by short optical pulses witharbitrary pulse area and detuning from the trion resonance. The interactionwith an external longitudinal magnetic field and the hyperfine interaction withthe nuclear spin bath is considered in both the ground and excited (trion)states of the quantum dots. We analyze how the spin inertia signal depends onthe magnetic field (polarization recovery) and on the modulation frequency ofthe helicity of the pump pulses as well as on their power and detuning. Inparticular, we elaborate how approaching the saturation limit of the spinpolarization influences the measurements. The quantitative description of spininertia measurements will enable the determination of the parameters of spindynamics such as the spin relaxation times in the ground and excited states andthe parameters of the hyperfine interaction. Finally, we predict the emergenceof resonant spin amplification due to the transverse components of the nuclearspin fluctuations, which manifests itself as oscillations of the spinpolarization as a function of the longitudinal magnetic field.
