Martensitic Transformation and Barocaloric Effect in Co-V-Ga-Fe Paramagnetic Heusler Alloy
Metals, 2022 In the present study, polycrystalline Co50V34Ga16−xFex (1≤x≤2) quaternary Heusler alloys were fabricated by the arc-melting method. It was found that they undergo a paramagnetic martensitic transformation (MT) from the L21-type cubic austenitic structure

Caloric effects around phase transitions in magnetic materials described by ab initio theory : the electronic glue and fluctuating local moments [PDF]
, 2020 We describe magneto-, baro-, and elastocaloric effects (MCEs, BCEs, and eCEs) in materials, which possess both discontinuous (first-order) and continuous (second-order) magnetic phase transitions.

Reversible adiabatic temperature changes at the magnetocaloric and barocaloric effects in Fe49Rh51 [PDF]
, 2015 We report on the adiabatic temperature changes (Delta T) associated with the magnetocaloric and barocaloric effects in a Fe49Rh51 alloy, For the magnetocaloric effect, data derived from entropy curves are compared to direct thermometry measurements.

Colossal barocaloric effects in the complex hydride Li[Formula: see text]B[Formula: see text]H[Formula: see text]. [PDF]
Sci Rep, 2021 AbstractTraditional refrigeration technologies based on compression cycles of greenhouse gases pose serious threats to the environment and cannot be downscaled to electronic device dimensions. Solid-state cooling exploits the thermal response of caloric materials to changes in the applied external fields (i.e., magnetic, electric and/or mechanical ...

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.

Solid-State Heating Using the Multicaloric Effect in Multiferroics
Magnetochemistry, 2021 The multicaloric effect is defined as the adiabatic reversible temperature change in multiferroic materials induced by the application of an external electric or magnetic field, and it was first theoretically proposed in 2012. The multicaloric effects in
