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.

Recent developments on the cyclic stability in elastocaloric materials
Materials & Design, 2020 Solid-state cooling based on elastocaloric effect (eCE), i.e., a temperature change coupled to an applied uniaxial stress in elastocaloric materials (eCMs), is an emerging refrigeration technology which has a great potential to replace the conventional ...

Elastocaloric effect with a broad temperature window and low energy loss in a nanograin Ti-44Ni-5Cu-1Al (at%) shape memory alloy [PDF]
, 2021 Superelastic Ti-Ni-based shape memory alloys are promising elastocaloric materials for solid-state refrigeration. In this paper, we studied the mechanical properties and elastocaloric effect of a severely cold rolled Ti-44Ni-5Cu-1Al (at.%) alloy composed

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.

Frustrated magnetism and caloric effects in Mn-based antiperovskite Nitrides : Ab Initio theory [PDF]
, 2017 We model changes of magnetic ordering in Mn-antiperovskite nitrides driven by biaxial lattice strain at zero and at finite temperature. We employ a non-collinear spin-polarised density functional theory to compare the response of the geometrically ...

Superelastic behavior and elastocaloric effect in a Ni51.5Fe21.5Ga27.0 ferromagnetic shape memory single crystal under compression [PDF]
, 2022 Ni51.5Fe21.5Ga27.0 single crystals have been subjected to different heat treatments resulting in a different degree of L21 ordering. Superelastic response has been measured at different temperatures in compression mode.
