Elastocaloric, barocaloric and magnetocaloric effects in spin crossover polymer composite films [PDF]

Nature Communications
Giant 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.
