A Solid-to-Solid 2D Model of a Magnetocaloric Cooler with Thermal Diodes: A Sustainable Way for Refrigerating

Energies, 2023
Solid-state caloric cooling is a viable route toward a more sustainable way of refrigerating. The refrigerants are solid-state materials with a caloric effect detectable by measuring a temperature variation through an external-field intensity change. The

Study of magnetocaloric effect in half-metallic ferromagnet Co3Sn2S2

Results in Physics, 2018
We have investigated the magnetocaloric effect of a shandite-type half-metal ferromagnet Co3Sn2S2. The magnetic entropy change -ΔSM(T,H) can be well scaled by the scaling relations, indicating that the magnetic ordering transition is of second order. The

Specific heat and magnetocaloric effect in UNiGa [PDF]

Physica B: Condensed Matter, 1993
Abstract Temperature dependence of the specific heat was measured on a single crystal of UNiGa in magnetic fields. The value γ =40.9 mJ/mol K 2 does not change with the field-induced transition. The magnetic entropy is larger in the high-field (ferromagnetic) state (0.55× R In2) than in the AF ground state (0.50× R In2).

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Magnetocaloric studies of the peak effect in Nb [PDF]

Physical Review B, 2007
We report a magnetocaloric study of the peak effect and Bragg glass transition in a Nb single crystal. The thermomagnetic effects due to vortex flow into and out of the sample are measured. The magnetocaloric signature of the peak effect anomaly is identified.
