Abstract
Piezoelectric force microscopy has been enhanced by coplanar epitaxial electrodes to detect and manipulate the striped ferroelectric domain structure of a multiferroic BiFe O3 thin film grown on single-crystalline DySc O3. Time-resolved imaging revealed ferroelastic (71° and 109°) switching of domains in a needlelike region that grew from one electrode toward the other in a uniform electric field, and demonstrated reversible rotation of the 71° domain stripe orientation in a nonuniform field. Purely ferroelectric (180°) switching was suppressed by the geometry of the electrodes. The extendibility of this apparatus opens the door toward magnetoelectric domain imaging. © 2007 American Institute of Physics.
