Abstract

Large magnetoresistance (MR) has been observed in Ni1- x S (x=-0.02, -0.01, 0, 0.01, 0.02 and 0.03). The MR in a magnetic field of 4 T was found to be equal to 770% at 290 K for x=-0.02, 920% at 283 K for x=-0.01, 1530% at 268 K for x=0, 1040% at 230 K for x=0.01, 730% at 257 K for x=0.02 and 660% at 87 K for x=0.03. The large MR was found to be due to a magnetic field-induced magnetic and electrical transition from an antiferromagnetic (AFM) anomalous-metal phase to a paramagnetic (PM) metal phase.
