Inverse barocaloric effects in ferroelectric BaTiO3 ceramics [PDF]
APL Materials, 2016 We use calorimetry to identify pressure-driven isothermal entropy changes in ceramic samples of the prototypical ferroelectric BaTiO3. Near the structural phase transitions at ∼400 K (cubic-tetragonal) and ∼280 K (tetragonal-orthorhombic), the inverse barocaloric response differs in sign and magnitude from the corresponding conventional electrocaloric ...

Barocaloric effect in the magnetocaloric prototype Gd5Si2Ge2
Applied Physics Letters, 2012 We report on calorimetric measurements under hydrostatic pressure that enabled us to determine the barocaloric effect in Gd5Si2Ge2. The values for the entropy change for moderate pressures compare favourably to those corresponding to the magnetocaloric effect in this compound.

Barocaloric effect in ferroelastic fluorides and oxyfluorides [PDF]
Ferroelectrics, 2016 Using the data about the temperature - pressure phase diagram and the phase transition entropy at ambient and high pressure, intensive and extensive barocaloric effects were analyzed in the region of single and successive order-disorder phase transitions in fluorides and oxyfluorides with the elpasolites-cryolite structure.
