The elasticity of minerals is central to our understanding of the structure and properties of the
Earth, and other planets. In the last half-century, and in particular within the last 15 years …

Landau-type theories describe the observed behaviour of phase transitions in ferroelastic
and co-elastic minerals and materials with a high degree of accuracy. In this review, the …

A marked change in anelastic properties, namely, elastic softening accompanied by
increased damping, has been observed in a single crystal of SrTiO 3 below∼ 50 K by …

Pinned and mobile ferroelastic domain walls are detected in response to mechanical stress
in a Mn3+ complex with two-step thermal switching between the spin triplet and spin quintet …

Ferroelectric materials find application in numerous electronic devices and are continuously
enabling the development of new technologies. Their versatility is intimately related to the …

The ferroelastic domain processes responsible for low-frequency anelasticity in LaAlO 3
have been investigated using dynamical mechanical analysis in three-point bend geometry …

We have studied the atomic structure of [001] 90 rotation twin walls in orthorhombic CaTiO 3
(symmetry Pbnm) at low temperature (10 K) and their effects on oxygen vacancies. The wall …

Resonant ultrasound spectroscopy (RUS) provides a window on the pervasive influence of
strain coupling at phase transitions in perovskites through determination of elastic and …

The dynamic response of ferroelastic twins to an alternating stress has been studied in situ
at high temperature using a stroboscopic x-ray diffractometer and combined dynamical …

The structure of twin walls and their interaction with defects has important implications for the
behaviour of a variety of materials including ferroelectric, ferroelastic, co-elastic and …
