Comparison of the temperature- and pressure-dependent behavior of the crystal structure of CrAs
Abstract
<jats:p>The crystal structure of CrAs was investigated using synchrotron X-ray single-crystal diffraction for separate dependences on temperature (30–400 K) and on pressure (0–9.46 GPa). The isosymmetrical magnetostructural phase transition at <jats:italic>T</jats:italic><jats:sub>N</jats:sub> = 267 K can induce a change in the microstructure by twinning due to a crossing of the orthohexagonal setting of the unit-cell parameter ratio <jats:italic>c</jats:italic>/<jats:italic>b</jats:italic>. Within the crystal structure, one particular Cr–Cr distance exhibits anomalous behavior in that it is nearly unaffected by temperature and pressure in the paramagnetic phase, which is stable above 267 K and at high pressures. The distinction of this shortest Cr–Cr distance might be of importance for the superconducting properties of CrAs.</jats:p>
