Magnetocaloric cascade and method for fabricating a magnetocaloric cascade

A method for fabricating a magnetocaloric cascade, comprising:

• fabricating a sequence of different 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 are fabricated so as to exhibit 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.
