摘要： PROBLEM TO BE SOLVED: To hold low temperature specific heat characteristics of a race earth magnetic cold storage material and improve chemical stability by forming an oxide of Nd, Ho, Gd, and Br different from rare earth elements Ni, Co, and Cu on the surface of a single rare earth element or a rare earth element compound of any of Ni, Co, and Cu. SOLUTION: Cold storage material grains are formed of a single race earth element, such as a single unit of Y, La, Ce, Sm or a compound of any of the above rare earth elements and at least one kind of metal selected from Ni, Co, and Cu. The surface of the cold storage material grains is constructed of at least one kind of oxides of Nd, Ho, Gd, and Br different from the rare earth elements forming the Grains. There is used Er3 Ni for example as a compound forming a main composition of the grains which is desired to be formed into a shape of the average particle diameter or a fiber diameter of about 1 to 2000μm. With the shape smaller than that described above the grains easily flow out from the cold storage unit but with the shape larger than that heat returning effect is lowered. Chemical stability is improved by forming the surface of the cold storage matter with a coating layer of an oxide of a rare earth element.
