Abstract
We studied the effect of Ni incorporation on the magnetic properties of (formula presented) (formula presented) using resistivity, susceptibility, and magnetization measurements under high pressure and magnetic field. With increasing pressure antiferromagnetic transition temperature (formula presented) of CeSb increases continuously leading to a high pressure phase. Similarly, (formula presented) of (formula presented) increases with pressure for (formula presented) while increasing pressure weakens a Cr-like anomaly found in the resistivity of (formula presented) Interestingly, resistivity of (formula presented) 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 (formula presented) and (formula presented) begin to appear with pressure too. On the other hand, pressure effects in both resistivity and magnetization of (formula presented) and (formula presented) are different from those of (formula presented) and (formula presented) We discuss these findings with regard to possible Ni-induced changes in the nature of the magnetic interactions of CeSb.
