Elastic precursor effects during the Ba${}_{1-x}$Sr${}_x$TiO${}_3$ ferroelastic phase transitions

Francesco Cordero, Francesco Trequattrini, Paulo Sergio da Silva +3

Elastic softening in the paraelastic phases of Ba${}_{1-x}$Sr${}_x$TiO${}_3$ is largest near the transition temperatures and decreases on heating smoothly over extended temperature r…
