摘要：

The effect of cobalt substitution on the hard magnetic properties of NdFeC-type ingot magnets was studied. It was found that cobalt substitution led to a significant decrease in the field strength needed to magnetize the ingot magnets. A simple production route is described which leads to an isotropic ingot magnet with (BH(max) = 70 kJ m-3, B(R) = 0.65 T and (J)H(c) = 800 kA m-1. The temperature coefficient (beta = -0.6% K-1) of these magnets is the same as that of sintered NdFeB-type magnets.
