A the magnetically anisotropic magnetic powder having an average particle size of 1-1000 .mu.m and made from a magnetically anisotropic R-TM-B-Ga or R-TM-B-Ga-M alloy having an average crystal grain size of 0.01-0.5 .mu.m, wherein R represents one or more rare earth elements including Y, TM represents Fe which may be partially substituted by Co, B boron, Ga gallium, and M one or more elements selected from the group consisting of Nb, W, V, Ta, Mo, Si, Al, Zr, Hf, P, C and Zn. This is useful for anisotropic resin-bonded magnet with high magnetic properties.

O pó magnético magnètica anisotropic que tem um tamanho de partícula médio do mu.m 1-1000 e feito de uma liga magnètica anisotropic de R-TM-B-Ga ou de R-TM-B-Ga-M que tem um tamanho de grão de cristal médio de 0.01-0.5 mu.m, wherein R representa um ou mais elemento da terra rara including Y, TM representa o Fe que podem parcialmente ser substituídos por Co, por boro de B, por gallium de Ga, e por M um ou mais elemento selecionado do grupo que consiste no Nb, no W, no V, na Ta, no Mo, no silicone, no al, no zr, no Hf, no P, no C e no zn. Isto é útil para o ímã resina-ligado anisotropic com propriedades magnéticas elevadas.
