Elastocaloric, barocaloric and magnetocaloric effects in spin crossover polymer composite films. [PDF]
Nat CommunGiant barocaloric effects were recently reported for spin-crossover materials. The volume change in these materials suggests that the transition can be influenced by uniaxial stress, and give rise to giant elastocaloric properties.

Giant elastocaloric effect at low temperatures in TmVO4 and implications for cryogenic cooling. [PDF]
Proc Natl Acad Sci U S A, 2023 Adiabatic decompression of para-quadrupolar materials has significant potential as a cryogenic cooling technology. We focus on TmVO$_4$, an archetypal material that undergoes a continuous phase transition to a ferroquadrupole-ordered state at 2.15 K ...

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.

Dependence of T$_{c}$ of YBa$_{2}$ Cu$_{3}$ O$_{6.67}$ on in-plane uniaxial stress [PDF]
, 2022 We probe the effect on $T_c$ of in-plane uniaxial stress applied to the high-temperature superconductor $YBa_2Cu_3O_{6.67}$. We find a highly anisotropic response.
