DOIAbstract
We report here the synthesis and magnetic properties of a new quaternary magnetic borocarbide YbNiBC. The material forms in the LuNiBC-type structure with lattice parameters a=3.503 Å and c=7.556 Å. From magnetic susceptibility and heat capacity measurements we find that YbNiBC orders magnetically at Tm~4 K. As a reference material, we have also synthesized GdNiBC and find that it orders magnetically at ~14 K which is consistent with an earlier report. Tm of YbNiBC is anomalously higher than that expected on the basis of de Gennes scaling
