Measuring the thermal expansion of solids: How is it done, and how<br />
can it be used to study phase transitions?<br />
John J. Neumeier<br />

We have developed an instrument for measuring the thermal expansion of solid<br />
materials, with a resolution of about 0.1 angstroms. It has been used to measure very<br />
complex materials such as quasi‐one‐dimensional compounds, important magnetic<br />
materials, superconductors and some elements. The results reveal a number of surprises<br />
as well as important information connecting structural and physical properties. In this<br />
presentation, I’ll describe the instrument in detail, highlight some results, and describe<br />
how thermal expansion can be used as a tool to study phase transitions.<br />
