Magnetic field-induced magnetic and electrical transition from the antiferromagnetic nonmetal phase to the paramagnetic metal phase takes place in Ni[sub 1-x]Fe[sub x]S (x=0, 0.12, 0.2, and 0.3). Large magnetoresistance (MR) was observed near room temperature, MR=730% for x=0.12 at 299 K in a magnetic field of 4 T. The large MR is related to the field-induced nonmetal-metal transition. © 2001 American Institute of Physics.
