In the course of a search for new permanent-magnet materials, several studies were performed on the magnetic behavior of the family of R-Co-B system. In this investigation these studies were extended to RCo/sub 12/B/sub 6/ systems. These compounds crystallize in a rhombohedral SrNi/sub 12/B/sub 6/-type crystal structure. It was reported that SmCOP/sub 12/B/sub 6/ has a Curie temperature of 708 K and a saturation magnetization, Ms=0.108 T. Our investigation indicates that RCo/sub 12/B/sub 6/ compounds for R= yttrium, cerium, praseodymium, neodymium, samarium, gadolinium and dysprosium are nonmagnetic at room temperature.
