Thermal Expansion of ScF$_{\mathrm{3}}$.

ORAL

Abstract

ScF$_{\mathrm{3}}$ is an insulator, has a cubic crystal structure, and exhibits negative thermal expansion over a very wide temperature range. We will present and discuss thermal expansion measurements made with capacitive and fiber-Bragg-grating dilatometers.
