The antiferromagnetic ordering temperature decreases with increasing pressure and the pressure-induced ordered phase appears above 1.4 GPa. Through the utilization of high-quality single crystals, we have discovered the anomalous Hall effect and tiny spontaneous magnetization, 0.02\u03bcB\/Mn, in the pressure-induced ordered phase. These findings indicate that \u03b1-Mn is a good material to study the anomalous Hall effect originated from the Berry curvature.
