Outstanding caloric performances for energy-efficient multicaloric cooling in a Ni-Mn-based multifunctional alloy

Influence of microstructure on the application of Ni-Mn-In Heusler compounds for multicaloric cooling using magnetic field and uniaxial stress

“…Several studies of Ni-Mn-based Heusler compounds show that cyclic caloric effects can be largely tuned by a simultaneous or sequential application of magnetic and mechanical fields [17][18][19]. In a recent work, we demonstrated that the giant magnetocaloric effect in Ni-Mn-In can be doubled for moderate field changes of 1 T magnetic field when at the same time a stress of 40 MPa is removed [20].…”

Microstructure engineering of metamagnetic Ni-Mn-based Heusler compounds by Fe-doping: A roadmap towards excellent cyclic stability combined with large elastocaloric and magnetocaloric effects

“…The superior performance of Fe6 and Fe8 is also outlined when the number of cycles and the corresponding cyclic ΔTad upon unloading are compared to other metamagnetic shape-memory materials such as Ni-Mn-Ga- [69][70][71][72] , Ni-Mn-In- [30,31,[73][74][75][76][77], Ni-Mn-Sn- [67,78,79], Ni-Mn-Ti- [80] and Ni-Mn-Al-based [81] alloys (see Figure 10(d)). While the cyclic elastocaloric effect is maintained, the cyclability is increased by almost one order of magnitude.…”

“…This way, even larger cyclic caloric effects can be achieved as compared to their single caloric counterparts. ) with other metamagnetic shape-memory materials (Ni-Mn-Ga- [69][70][71][72] , Ni-Mn-In- [30,31,[73][74][75][76][77], Ni-Mn-Sn- [67,78,79], Ni-Mn-Ti- [80] and Ni-Mn-Al-based [81] alloys) upon cyclic loading. The number of cycles corresponds to the maximum values reported in the literature independent on the occurrence of failure.…”

Ni-Mn-Sn-Cu Alloys after Thermal Cycling: Thermal and Magnetic Response

“…Likewise, for the magnetic refrigeration or shape memory applications it is necessary to check the stability of the functional response after cycling. The mechanical cycling from Ni-Mn-based alloys shows that the mechanical stability is linked to the good geometrical compatibility at the interphase between austenite and martensite [19]. In our study, we produce three Ni-Mn-Sn-(Cu) Heusler alloys.…”
