An analysis is made of mechanisms of the formation and redistribution of space charge which influence the dielectric hysteresis in SrTiO3. The excess space charge density in SrTiO3 at 4.2 K is estimated by comparing calculated and experimental dependences of the initial capacitance and the dielectric hysteresis parameter ΔC/C0 as a function of the crystal thickness.
