PROBLEM TO BE SOLVED: To provide magnet powders and an isotropic bonded magnet which can provide a magnet superior in a molding property and magnetic characteristics. SOLUTION: Magnet powders by being subjected to quenching by spraying, a fusion of an alloy composition represented by Rx(Fe1-yCoy)100-x-z-wBzAlw(where R is at least one kind of rare-earth element, x is 7.1 to 9.9 atomic %; y is 0 to 0.30 atomic %; z is 4.6 to 6.9 atomic %; w is 0.02 to 1.5 atomic %) for obtaining magnet powders. Its constitution is a composite one, having a hard magnetic phase and a soft magnetic phase as main phases. |
