Abstract
The effects of the alignment degree of grain ''easy-axes'' on the hard magnetic properties of NdFeB sintered magnets have been investigated. The results show that the remanence polarisation J(r) increases monot onously with an enhancement in the degree of grain alignment (i.e. dec rease in the orientation coefficient sigma), whereas the intrinsic coe rcivity H-j(c) decreases monotonously. This dependence leads to a non- monotonic behaviour of the magnetic-inductive coercivity H-b(c) and a saturation of the maximum energy product (BH)(max).
