- Description
- The magnetic and transport properties of the quaternary intermetallic HoNiBC compound (space group <math>P4/nmm, a = 3.563(1) \AA , c = 7.546(1)\AA )</math> were studied for <math>1.2K \leq T \leq 300K\!\,</math> and <math>H \leq 80 kOe\!\,</math>. The compound orders antiferromagnetically at 9.8(3)K and, in the ordered state, the Ho-moment saturates to 8.5(1)µB. In contrast with the structurally-related reentrant superconductor <math>HoNi_2B_2C\!\,</math>, neither superconductivity is found nor are there indications for a helical ground-state in the whole temperature range. These features are attributed, respectively, to the positioning of the Fermi level at a DOS minimum and the presence of the HoC double layers that inhibits the establishment of a helical spin arrangement.
