Formation of 90° elastic domains during local 180° switching in epitaxial ferroelectric thin films
A cylindrical 180° domain was stabilized by the formation of 90° domains to relax stress that arises due to the opposite signs of the converse piezoelectric effects in the switched 180° domain and the unswitched film surrounding. It was found that the formation of 90° domains can be effective mechanism for the piezostress relaxation in 180° domains and their stabilization.
