Negative Thermal Expansion in Open Perovskites near the Precipice of Structural Stability
(2018)
Negative thermal expansion (NTE) describes the anomalous propensity of materials to shrink when heated. Since its discovery, the NTE effect has been found in a wide variety of materials with an array of magnetic, electronic ...
Large isotropic negative thermal expansion above a structural quantum phase transition
(2015-10-01)
Perovskite structured materials contain myriad tunable ordered phases of electronic and magnetic origin with proven technological importance and strong promise for a variety of energy solutions. An always-contributing ...
Negative thermal expansion near two structural quantum phase transitions Connor
(2017-12-18)
Recent experimental work has revealed that the unusually strong, isotropic structural negative thermal
expansion in cubic perovskite ionic insulator ScF3 occurs in excited states above a ground state tuned very near a ...
