Simulation of nanoscale domain growth for ferroelectric recording

The growth process of nm-scale polarization domains is of great interest from a physical point of view and is also important in the design of ferroelectric recording, which is expected to be a high-density information recording method. To clarify the growth of nanoscale domains in probe-based ferroe...

description	The growth process of nm-scale polarization domains is of great interest from a physical point of view and is also important in the design of ferroelectric recording, which is expected to be a high-density information recording method. To clarify the growth of nanoscale domains in probe-based ferroelectric recording, a simulation method based on the time-dependent Ginzburg–Landau equation has been developed. In this method, wall pinning is included in the phenomenological free energy by using a coercive field.
