摘要：

It has been found that the arc-melted NdFe10.7-xCoxTi1.3 (x=0/2/4/6) alloys have nearly single phase of ThMn12-type structure except the small amount of (Fe,Co)2Ti (or Fe2Ti) and alpha-Fe phases. The ThMn12-type phase forms as square prisms and (Fe,Co)2Ti (or Fe2Ti) exist between the grain boundaries as particles. Nitrification of this alloy system considerably increases the anisotropy field and Curie temperature. The dependence on cobalt content of the magnetic properties before and after the nitrification treatments shows almost the same trend; the Co-substitution increases the Curie temperature but decreases die anisotropy field. In the nitride system studied, NdFe10.7Ti1.3Ny has the highest anisotropy field of about 6370 kA/m (80 kOe).
