dc.description.abstractThe search for new superconductors (SC) represents an exciting field in condensed matter physics. Recently, CeNi Bi-0:8(2) has been reported as a new bulk SC (Tc similar to 4:2K) in which Ni vacancies play an essential role for the emergence of superconductivity. Here we report experiments of magnetic susceptibility and heat capacity combined with energy dispersive X-ray spectroscopy analysis on CeNixBi2-y (x = 0:62;0:70;0:74;0:78) single crystals. Our data show a systematic enhancement of the antiferromagnetic transition temperature (T-N) with x, as well as the low temperature Ce3+ magnetic anisotropy. In particular, we find that the crystal-field ground state doublet becomes more isolated from the excited states as one approaches the Ni-rich end. As a consequence of such subtle crystal-field evolution, our analyses suggest that both the magnetic frustration and the hybridization between Ce3+ 4f and conduction electrons are decreasing along the series. In addition, SC transitions are observed in both La and Ce members with no bulk signature, strongly indicating the presence of impurity SC phasespt_BR
