Abstract

Magnetically anisotripic powder and resin-bonded magnets made therefrom have 'flattened' crystal grains of an R-TM-B-M system alloy with preferably (c)/(a) greater than 2, where (c) is the grain size perpendicular to the C-axis and (a) the grain size parallel to the C-axis. The 'flattened' grains are produced by plastically deforming a green compact of flakes formed by rapidly-quenching an alloy melt, and then crushing the plastically deformed body. In the allow system, R is at least one of the rare earth elements including Y, TM is Fe or Fe a part of which has been substituted with Co, B is boron, and M is an additive selected from Si, Al, Nb, Zr, P and C.
