Abstract Domain wall motion is detected for the first time during the transition to a ferroelastic
and spin state ordered phase of a spin crossover complex. Single‐crystal X‐ray diffraction …

We design a microscopic model for switchable molecular solids (eg, spin crossover), based
on the elastic properties of a discrete lattice made of switchable sites, denoted high spin …

The observation and the study of first-order phase transitions in cooperative spin-crossover
(SCO) solids exhibiting hysteresis behaviours are of particular interest and currently …

Molecules with bistable spin states are widely studied because of their importance to the
natural world and their potential applications as molecular scale switches. In molecular …

The nucleation, growth, and propagation of like-spin domains in spin-crossover materials
was investigated during the relaxation process of a metastable HS state at low temperature …

We report the existence of anomalous metamagnetic fluctuations in the vicinity of the
dynamic phase transition (DPT) that do not occur for the corresponding thermodynamic …

Elastic modeling of spin-crossover materials has boomed remarkably these last years.
Among these models, the electro-elastic model combining spin and lattice degrees of …

The elastic interaction, induced by the lattice distortion due to the difference of the molecular
size, causes an effective long-range interaction. In spin-crossover (SC) compounds, local …

The present work is devoted to the spatio-temporal investigations of spin-crossover lattices
during their thermal relaxation from high-to low-spin state. The analysis is performed using …

We propose here a new theoretical treatment of the spatiotemporal properties in spin-
crosser solids, based on the expansion of the free energy taking into account the spatial …
