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.The application relates to a layered magnetocaloric material being a metallic solid, comprising at least three interconnected layers (1, 2, 3) formed from binary intermetallic compounds, the compounds containing atoms of rare earth elements selected from the group of lanthanides designated as L and Ni atoms, and each layer furthermore comprising a separate binary intermetallic compound: (1) L1Ni2, (2) L2Ni2 and (3) L3Ni2, wherein L1, L2 and L3 are different. The application further relates to a method of producing a layered magnetocaloric material by synthesis, powder preparation and sintering, as well as to use in low-temperature magnetic refrigeration.
