Abstract

Zgłoszenie dotyczy warstwowego materiału magnetokalorycznego stanowiącego metaliczne ciało stałe, zawierającego co najmniej trzy połączone ze sobą warstwy (1, 2, 3), utworzone z binarnych związków międzymetalicznych, przy czym związki zawierają atomy pierwiastków ziem rzadkich, wybranych z grupy lantanowców oznaczonych jako L oraz atomy Ni, a ponadto każda z warstw zawiera odrębny binarny związek międzymetaliczny: (1) L1Ni2, (2) L2Ni2 oraz (3) L3Ni2, przy czym L1, L2 i L3 są różne. Zgłoszenie dotyczy ponadto sposobu wytwarzania warstwowego materiału magnetokalorycznego poprzez syntezę, przygotowanie proszków i spiekanie, a także zastosowania w niskotemperaturowym chłodnictwie magnetycznym.
