Abstract

Propagation process of electrically induced fatigue cracking in BaTiO3 single crystal has been studied using atomic force microscope (AFM). The results show that alternating electric field generates a random domain switching around indentation cracks instead of a cyclic domain switching and an arrest indentation crack can be re-initiated by applying either positive or negative alternating electric field.
