Coupling of the lattice and superlattice deformations and hysteresis in thermal expansion for the quasi one-dimensional conductor TaS${}_3$

A. V. Golovnya, V. Ya. Pokrovskii, P. M. Shadrin

An original interferometer-based setup for measurements of length of needle-like samples is developed, and thermal expansion of o-TaS${}_3$ crystals is studied. Below the Peierls tra…
