| 英文摘要 | Barocaloric (BC) materials are a category of solid-state refrigerants with great potential for use in future refrigerators. Here we reported the double BC effects in ferroelastic Pb3V2O8. Upon heating, it undergoes a transition from the distorted monoclinic alpha phase to monoclinic beta phase at 273 K, and then the beta phase transfers to the rhombhedral gamma phase at 375 K. Applying pressure shifts the alpha-beta and beta-gamma transitions to higher and lower temperatures, respectively. By applying a pressure of 100 MPa, the isothermal entropy changes are -6.4 JK(-1)kg(-1) and 11.6 JK(-1)kg(-1) for the alpha-beta and beta-gamma transitions, corresponding to the adiabatic temperature change of 5.9 K and -9.7 K, respectively. The conventional and inverse BC effects are attributed to the lattice expansion and contraction during the alpha-beta and beta-gamma transitions, respectively. Such double BC effects enable automatic switching between cooling and heating modes according to the changes of ambient temperature. |
