Show affiliationsThe electrical resistivity at low temperature of metallic NiS2-xSex is measured at a temperature between 4.2 and 300K under high pressure up to 15 kbar. The resistivity is found to obey an expression rho = rho 0+ATn and the coefficient of A has a maximum at the critical boundary of antiferromagnet. The index n decreases from 2.0 to 1.6 as one approaches the critical boundary from the paramagnetic phase. These results seem to be explained by recent theoretical works based on the spin fluctuations.
