Soliton Generation in Negative Thermal Expansion Materials
Frontiers in Materials, 2021 Strain solitons have been observed statically in several 2D materials and dynamically in substrate materials using ultrafast laser pulses. The latter case relies on lattice relaxation in response to ultrafast heating in a light-absorbing transducer ...

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.

Negative thermal expansion in ZnF2 [PDF]
Applied Physics Letters, 2011 We have investigated temperature dependence of the lattice parameters and the unit cell volume of ZnF2 by neutron diffraction and have discovered negative thermal expansion (NTE) at low temperature. To understand why this simple compound exhibits NTE we performed first principle calculations.

Negative thermal expansion property of Sm1−xCuxMnO3−δ
Journal of Materials Research and Technology, 2021 The negative thermal expansion (NTE) property of a Sm1−xCuxMnO3−δ (x = 0.05, 0.1, 0.15, 0.2) material was studied in detail. The Sm1−xCuxMnO3−δ was synthesized by a solid phase method.

Negative thermal expansion and phase transition of low-temperature Mg2NiH4
Journal of Magnesium and Alloys, 2023 The negative thermal expansion (NTE) phenomenon is of great significance in fabricating zero thermal expansion (ZTE) materials to avoid thermal shock during heating and cooling.

Negative thermal expansion materials † [PDF]
Journal of the Chemical Society, Dalton Transactions, 1999 The ZrW2O8 family of materials has been shown to exhibit the unusual property of negative thermal expansion over a wide temperature range. α-ZrW2O8 itself shows negative thermal expansion from 2 K to 1443 K with a coefficient of thermal expansion α1 of -9.1×10-6 K-1 between 2 and 300 K. This behaviour can be related to the unusual structure of these

Understanding the role of guest ions in the control of thermal expansion of FeFe(CN)6
Results in Physics, 2022 Understanding the role of guest species in framework materials is important to successfully achieve the control of thermal expansion. In this work, the thermal expansion of the Prussian blue analogue FeFe(CN)6 has been effectively tailored from negative,

Journal of Physics: Condensed Matter, 2005 There has been substantial renewed interest in negative thermal expansion following the discovery that cubic ZrW2O8 contracts over a temperature range in excess of 1000 K. Substances of many different kinds show negative thermal expansion, especially at low temperatures.
