A kink was observed near 20 kOe in the field dependence of the magnetization in a single-grained alpha-Mn without a magnetic hysteresis below the Neel temperature in an accurate magnetization measurement below 80 kOe. It was observed along ,  and  crystallographic directions. The field dependence of the magnetization above 40 kOe extrapolates to positive finite magnetization at null field. The kink suggests a weak metamagnetism induced by the external magnetic field. A small but clear anisotropy was observed between the weak-field susceptibilities along  and / directions. A previously reported large susceptibility anomaly was not affirmed between 90 and 270 kOe. (C) 2008 Elsevier B. V. All rights reserved.
