Anomalous thermal expansion, negative linear compressibility, and high-pressure phase transition in : Neutron inelastic scattering and lattice dynamics studies

We present temperature-dependent inelastic-neutron-scattering measurements, accompanied by ab initio calculations of the phonon spectra and elastic properties as a function of pressure to quantitatively explain an unusual combination of negative thermal expansion and negative linear compressibility...
