PROBLEM TO BE SOLVED : To provide powder for magnets which is high in the degree of crystal grain orientation and superior in magnetic property. SOLUTION : Powder for magnets comprises magnetic particles made of a rare earth-iron based alloy having a main phase including a rare earth-iron-based compound including a rare earth element and Fe. The magnetic particles have an aggregate structure formed by aggregation of many crystal grains of the main phase. In the crystal grains, the maximum crystal grain diameter is less than 1 μm, and the degree of orientation of the crystal grains is 60% or larger. The percentage of the magnetic particles having a particle diameter of 3-10 μm is 60 mass% or larger in the powder for magnets. COPYRIGHT : (C)2015, JPO&INPIT
