Uniaxial and hydrostatic pressure effects in <i>α</i>-RuCl<sub>3</sub> single crystals via thermal-expansion measurements
We present high-resolution thermal-expansion and specific-heat measurements of single crystalline α-RuCl3. An extremely hysteretic structural transition expanding over 100 K is observed by thermal-expansion along both crystallographic axes, which we attribute to a change of stacking sequence of the RuCl3 layers. Three magnetic transitions are observed, which we link to …
