Description
| - We report the low-temperature properties of 11 B-enriched single-crystal CrB 2 as prepared from high-purity Cr and B powder by a solid-state reaction and optical float zoning. The electrical resistivity, ρ xx , Hall effect, ρ xy, and specific heat, C, are characteristic of an exchange-enhanced Fermi liquid ground state, which develops a slightly anisotropic spin gap 220 K below T N = 88 K. This observation is corroborated by the absence of a Curie dependence in the magnetization for T 0 reported in the literature. Comparison of C with dρ xx /dT , where we infer lattice contributions from measurements of VB 2 , reveals strong antiferromagnetic spin fluctuations with a characteristic spin fluctuation temperature T sf 257 K in the paramagnetic state, followed by a pronounced second-order mean-field transition at T N , and unusual excitations around T N /2.
