Transmission electron microscopy image of the ferroelastic domain structure in a YBa2Cu3O7−y crystal (Rosová, 1999[link]). Courtesy of A. Rosová, Institute of Electrical Engineering, SAS, Bratislava. There are two systems (`complexes'), each of which is formed by almost parallel ferroelastic domain walls with needle-like tips. The domain walls in one complex are nearly perpendicular to the domain walls in the other complex.
