Influence of microstructure on the application of Ni-Mn-In Heusler compounds for multicaloric cooling using magnetic field and uniaxial stress
Lukas Pfeuffer, Adrià Gràcia-Condal, Tino Gottschall +12
Novel multicaloric cooling utilizing the giant caloric response of Ni-Mn-based metamagnetic shape-memory alloys to different external stimuli such as magnetic field, uniaxial stres…
Thermo-magnetic characterization of phase transitions in a Ni-Mn-In metamagnetic shape memory alloy
F. J. Romero, J. M. Martín-Olalla, J. S. Blázquez +4
The partially overlapped ferroelastic/martensitic and para-ferromagnetic phase transitions of a NiMnIn metamagnetic shape memory alloy have been studie…
Asymmetric electrocaloric effects in PbSc0.5Ta0.5O3 on field application and removal
E. Stern-Taulats, P. Lloveras, M. Barrio +6
Electrically driven thermal changes in PbSc0.5Ta0.5O3 bulk ceramics are investigated using temperature and electric-field dependent differential scanning calorimetry and infrared t…
Multicaloric effects in Metamagnetic Heusler Ni-Mn-In under uniaxial stress and magnetic field
Adrià Gràcia-Condal, Tino Gottschall, Lukas Pfeuffer +3
The world's growing hunger for artificial cold on the one hand, and the ever more stringent climate targets on the other, pose an enormous challenge to mankind. Novel, efficient an…
Suppression of acoustic emission during superelastic tensile cycling of polycrystalline NiTi
Guillaume F. Nataf, Michela Romanini, Eduard Vives +4
We investigate acoustic emission (AE) that arises during the martensitic transition in a polycrystalline specimen of the prototypical superelastic/elastocaloric alloy NiTi…
Colossal barocaloric effects near room temperature in plastic crystals of neopentylglycol
Pol Lloveras, Araceli Aznar, María Barrio +9
There is currently great interest in replacing the harmful volatile hydrofluorocarbon fluids used in refrigeration and air-conditioning with solid materials that display magnetocal…
