摘要：
An alloy is used for production of magnetic refrigeration material particles. The alloy contains La in a range of 4 to 15 atomic %, Fe in a range of 60 to 93 atomic %, Si in a range of 3.5 to 23.5 atomic % and at lease one element M selected from B and Ti in a range of 0.5 to 1.5 atomic %. The alloy includes a main phase containing Fe as a main component element and Si, and a subphase containing La as a main component element and Si. The main phase has a bcc crystal structure and an average grain diameter of 20 μm or less.
