    摘要： The present invention relates to the field of magnetic functional materials. The present invention discloses a use of a rare earth fluoride single crystal in magnetic refrigeration, a magnetic refrigeration method and a magnetic refrigeration device. A magnetocaloric material of the series is lithium rare earth fluoride, with the chemical formula of LiREF 4 , wherein RE is one or more of rare earth elements gadolinium, terbium, dysprosium, holmium, erbium, thulium and ytterbium. A magnetocaloric material single crystal of the series has extremely strong magnetic anisotropy. By applying a varying magnetic field of 0-20kOe along the easy magnetization axis direction of the magnetocaloric material, LiGdF 4 , LiTbF 4 , LiHoF 4 , LiDyF 4 , LiErF 4 , LiYbF 4 and LiTmF 4 obtained isothermal magnetic entropy changes of 50.35J·kg -1 ·K -1 , 21.12J·kg -1 ·K -1 , 24.98J·kg -1 ·K -1 , 24.45J·kg -1 ·K -1 , 21.95J·kg- 1 ·K -1 , 14.7J·kg -1 ·K -1 and 0.692J·kg -1 ·K -1 , respectively, at 1.8K, 4K, 4K, 1.8K, 1.8K, 1.8K, and 18K. Wherein, the thermal conductivity of LiTbF 4 and LiErF 4 reaches 50W·K -1 ·m -1 at 25K.
