摘要
A sintered R2M17 magnet is provided that comprises at least 70 Vol % of a Sm2M17 phase, wherein R is at least one of the group consisting of Ce, La, Nd, Pr, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm,;Yt, Lu and Y, and M comprises Co, Fe, Cu and Zr. In an area of the R2M17 sintered magnet of 200 by 200 μm viewed in a Kerr micrograph, an areal proportion of demagnetised regions after application of an internal opposing field of 1200 kA/m is less than 5% or less than 2%.
