Abstract

We report structural, magnetic, and magnetotransport properties of the two-dimensional chromium sulfide Cr₂S_2.92, which contains both Cr³⁺ and Cr²⁺ ions. Below its magnetic-ordering temperature (T_N=118 K), Cr₂S_2.92 exhibits a weak spontaneous magnetization with a maximum around 90 K and a value of 0.013(4) µ_B per Cr ion at 5 K. The resistivity and magnetoresistance exhibit pronounced local maxima around T_N (MR=48% in a field of 14 T). The magnetotransport properties are discussed in terms of magnetic-polaron formation.
