Stage: PROBLEM TO BE SOLVED: To provide a permanent magnet with improved magnetic properties and a method for manufacturing the same.SOLUTION: A method includes homogenizing a first population of particles of a first GBM alloy with a second population of particles of a second core alloy to form a composite alloy preform. The first GBM alloy is represented by the formula: ACbRxCoyCudMz, and the second core alloy is represented by the formula: G2Fe14B. The method also includes heating the composite alloy preform particles to form a population of mixed alloy particles, compressing the mixed alloy particles to form a green compact under an inert atmosphere and a magnetic field of suitable strength to align the magnetic particles in a common direction of magnetization, and sintering the green compact and annealing the sintered compact.SELECTED DRAWING: Figure 4A (Grant)
