abstract
We studied the effect of Ni incorporation on the magnetic properties of CeSbNix (0≤x≤0.35) using resistivity, susceptibility, and magnetization measurements under high pressure and magnetic field. With increasing pressure antiferromagnetic transition temperature (TN) of CeSb increases continuously leading to a high pressure phase. Similarly, TN of CeSbNix increases with pressure for x≤0.15 while increasing pressure weakens a Cr-like anomaly found in the resistivity of CeSbNi0.08. Interestingly, resistivity of CeSbNi0.08 under higher pressure becomes very similar to that of CeSb at ambient pressure. Magnetic hysteresis, metamagnetic transition, and saturation behavior, which are absent in the ambient-pressure magnetization of CeSbNi0.05 and CeSbNi0.08, begin to appear with pressure too. On the other hand, pressure effects in both resistivity and magnetization of CeSbNi0.15 and CeSbNi0.35 are different from those of CeSbNi0.05 and CeSbNi0.08. We discuss these findings with regard to possible Ni-induced changes in the nature of the magnetic interactions of CeSb.
