Recent magnetic resonance results suggest that MnIn 2S 4 is antiferromagnetic with a Néel point near liquid helium temperature, in disagreement with previously reported dc (direct current) susceptibility measurements. The resonance data suggest that these susceptibility measurements were made at an applied dc field comparable to or greater than the critical field. This would tend to obscure observation of a magnetic transition, since some of the spins would be “flopped.” The susceptibility measurements have been repeated at a much lower applied field. From these new measurements, a Néel temperature of 4.9°K is obtained, in agreement with the resonance data, and an exchange parameter of 1430 is computed.
