  • This work demonstrates super colossal barocaloric effect in one of the “simplest” materials—H2O, with a reversible entropy change as much as 728 J·kg-1·K-1 under a small pressure 0.1 GPa by adding a little amount of GdCl3. Neutron combined with molecular dynamics simulations revealed the mechanism and inferred that H-bond engineering can be an attractive approach for designing novel caloric materials.

  • First-principles calculations demonstrated that the substitution of In for Ge has a lower energy barrier for phase transition than the substitution of In for Co in MnCoGe alloys. ELF calculations further reveal the regulated hysteresis’s atomic coordination origin. This theoretical prediction is completely verified by combining neutron, magnetic and calorimetric measurements; consequently, a largely enhanced barocaloric effect has been achieved.
