Large elastic nonlinearities can lead to elastic hysteresis behavior, which defines
ferroelasticity in analogy to its sister ferroics: ferromagnetism and ferroelectricity …

Twin boundaries in ferroelastics and curved interfaces between crystalline and amorphous
zircon can, in principle, act as multiferroic structural elements and lead the way to the …

Defying the conventional wisdom regarding first-order transitions, solid-solid displacive
transformations are often accompanied by pronounced pretransitional phenomena …

The first-order diffusionless structural transition in Cu 67.64 Zn 16.71 Al 15.65 is
characterized by jerky propagation of phase fronts related to the appearance of avalanches …

Large-scale computer simulations of a simple model with a square-lattice topology, a small
shear deformation (4° shear angle), and open (free) boundary conditions show that domain …

Understanding the relationship between the structure and “giant” piezoelectric properties of
relaxor ferroelectric solid solutions (1–x) Pb (Mg 1/3 Nb 2/3) O 3–x PbTiO 3 [PMN–x PT] and …

In this Perspective, two interrelated new developments are discussed. The first relates to a
much better understanding of the actual movement of domain walls during switching …

The shape and orientation of twin walls are calculated within the limits of elasticity theory.
Single twin walls are oriented along lattice planes which are determined by the condition …

The non-smooth, jerky movements of microstructures under external forcing in minerals are
explained by avalanche theory in this review. External stress or internal deformations by …

Ferroelastic domain walls are typically twin interfaces. They contain a multitude of emerging
properties, including (super-) conductivity, polarity, optically activity, and photovoltaic …
