Abstract
Large magnetoresistance (MR) has been observed in Ni1-xS (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% a
t 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 magnet
ic field-induced magnetic and electrical transition from an antiferromagnet
ic (AFM) anomalous-metal phase to a paramagnetic (PM) metal phase.
