Giant Room‐Temperature Elastocaloric Effect in Ferroelectric Ultrathin Films

Advanced Materials, 2014
Environmentally friendly ultrathin BaTiO3 capacitors can exhibit a giant stress-induced elastocaloric effect without hysteresis loss or Joule heating. By combining this novel elastocaloric effect with the intrinsic electrocaloric effect, an ideal refrigeration cycle with high performance (temperature change over 10 K with a wide working-temperature ...

Giant elastocaloric effect in V-doped Ni–Mn–In alloys

Applied Physics Letters
Solid state elastocaloric refrigeration exploits the elastocaloric effect in shape memory alloys to achieve cooling, primarily depending on the entropy change of martensitic transformation (ΔStr). In this work, we demonstrate that replacing In by V leads

Combining magnetocaloric and elastocaloric effects in a Ni45Co5Mn37In13 alloy

Journal of Materials Science & Technology, 2021
Abstract Solid-state refrigeration technology has become a promising candidate to replace the traditional low-efficiency and environment-harmful vapor compression refrigeration. However, the narrow temperature region becomes a critical problem which hinders the practical applications of caloric materials to a refrigerator. Here, we report a potential

Room temperature elastocaloric effect in polycrystalline Ni51Mn34In8Sn7 alloy

Materials Letters, 2019
Abstract Room temperature elastocaloric effect as well as the effects of strain rate and loading stress have been studied in polycrystalline Ni51Mn34In8Sn7. The increase of strain rate reduces plastic deformation and lattice invariant strain, thus improving the superelasticity.
