Abstract
Nuclear magnetic resonance and magnetic susceptibility measurements have been made at 295° and 77°K on titanium‐cobalt alloys over a range of composition near the equiatomic value and also on ternary alloys near the composition Ti2NiCo. The measurements in TiCo suggest that there may be a small range of solid solution for cobalt‐rich alloys near the equiatomic composition. There is a large positive Knight shift for the Co59 resonance in all TiCo alloys. The Knight shift and the susceptibility are substantially larger at the lower temperature presumably due to a large contribution from an orbital interaction. For the ternary compounds both the Knight shift and the susceptibility are smaller, and it is postulated that the orbital contribution has been eliminated.
