摘要	Solid-state refrigeration based on the magneto- or mechano-caloric effect, including elasto- and barocaloric in ferroic phase transition materials is promising to replace the current vapor compression refrigeration in consideration of environmental-friendliness and energy-saving. However, both high driven field and small thermal changes in all of these caloric materials hinder the development of solid-state refrigeration. Here we report a giant baro-caloric effect near room temperature induced by a low hydrostatic pressure in Co-based Co51Fe1V33Ga15 Heusler alloy. The maximum adiabatic temperature change under the applied pressure change of Delta p = 0.1-100 MPa can be as high as Delta T-ad(Max) = 7.7 K (Delta T-ad(Max)/Delta preaches up to similar to 7.7 K kbar(-1)), surpassing the Delta T-ad(Max)/Delta pvalue reported hitherto in baro-caloric alloys. In addition, the microstructure is also studied by using the electron microscopes. Along with the austenite and martensite, the submicron V-rich particles are precipitated in this alloy, which are believed to account for enhancing mechanical properties.
