Elastocaloric-effect-induced adiabatic magnetization in paramagnetic salts due to the mutual interactions

Abstract The temperature change under adiabatic stress, i.e., the elastocaloric effect, is a well-understood phenomenon and of particular interest due to its potential application in alternative ways for refrigeration. Here, we demonstrate that in the regime of low-temperatures (a few mK) real param...
