Negative thermal expansion in solid deuteromethane [PDF]

Low Temperature Physics, 2020
The thermal expansion at constant pressure of solid CD4 III is calculated for the low-temperature region where only the rotational tunneling modes are essential and the effect of phonons and librons can be neglected. It is found that in mK region there is a giant peak of the negative thermal expansion.
