    Abstract: A magnetocaloric cascade contains a sequence of magnetocaloric material layers having different Curie temperatures TC, wherein the magnetocaloric material layers include a cold-side outer layer, a hot-side outer layer and at least three inner layers between the cold-side outer layer and the hot-side outer layer, and each pair of next neighboring magnetocaloric layers of the magnetocaloric cascade has a respective Curie-temperature difference amount ΔTC between their respective Curie temperatures, wherein the hot-side outer layer or the cold-side outer layer or both the hot-side and cold-side outer layer exhibits a larger ratio mΔSmax/ΔTC in comparison with any of the inner layers, m denoting the mass of the respective magnetocaloric material layer and ΔSmax denoting a maximum amount of isothermal magnetic entropy change achievable in a magnetic phase transition of the respective magnetocaloric material layer.

    Abstract: The invention relates to a magnetocaloric device, comprising a field generator, arranged to provide a changing external magnetic field and a magnetocaloric regenerator arrangement. The magnetocaloric regenerator arrangement comprises a magnetocaloric element, wherein the magnetocaloric element comprises magnetocaloric material, and wherein the magnetocaloric regenerator arrangement is arranged to be exposed to the changing external magnetic field of the field generator. Furthermore, the invention is characterized in that the magnetocaloric device further comprises an insulating means wherein the insulating means is arranged such that the magnetocaloric regenerator arrangement is hermetically surrounded by the insulating means.
