Elucidation of barocaloric effect in spin crossover compounds
Acta Crystallographica Section A Foundations and Advances, 2022 The search for new efficient materials and refrigeration mechanisms is a key challenge toreplace the conventional vapor compression technology. An attractive alternative technologyuses the caloric refrigeration cycle, which is based on the adiabatic temperature and isothermalentropy change upon tuning an external parameter such as pressure, electric ...

Tunable barocaloric effects of two-dimensional hybrid perovskite through carbon chain lengths [PDF]
APL MaterialsOrganic–inorganic hybrid perovskites have recently emerged as a promising class of barocaloric materials. The entropy change in such materials mainly originates from the order-to-disorder phase transition of the organic carbon chains.

Tunability of the spin reorientation transitions with pressure in NdCo5 [PDF]
, 2020 We present pressure-dependent magnetization measurements carried out in the domain of the spin reorientation transitions (SRTs) of a NdCo5 single crystal. The application of a hydrostatic pressure leads to a shift in the SRTs to higher temperatures. This

Neutron scattering of magnetocaloric and barocaloric materials [PDF]
SCIENTIA SINICA Physica, Mechanica & Astronomica, 2021 Caloric materials are systems that exhibit significant thermal effects at phase transitions induced by external fields like temperature, pressure, stress, magnetic fields, and so forth. They can be used for the solid-state refrigeration through a designated cooling cycle.
