Precursor Nanoscale Textures in Ferroelastics: Interplay between Anisotropy and Disorder

Abstract:

We study the effect of anisotropy and disorder on the morphology of precursor microstructures within a Ginzburg-Landau free energy framework. In addition, with increasing disorder at low anisotropy we find a crossover from a twinned state to a non-transforming frozen state. Results are compared with available experimental data.
