Abstract:	Stress-induced local polarization reversal was studied in La doped BiFeO3 ceramics under the action of indentation. Piezoresponse force microscopy was used for study of domain struc-ture before and after local polarization reversal. Two mechanisms of domain formation were revealed: (1) direct stress-induced and (2) stress mediated by grain clamping. Critical stress value for local polarization reversal was extracted from the dependence of the switched area on the applied loading force.
