• Resistivity of α-Mn alloys containing dilute V, Cr, Fe, Co, and Ni impurities was measured between 1.6 K and room temperature. T^2-dependence in resistivity was found below 10 K in these alloys. The anomalously large coefficient of T^2-term of 0.125 μΩcm/K^2 in low temperature resistivity of α-Mn was drastically influenced by addition of 1 at% V, Cr, Fe, Co and Ni impurities and the coefficient varies to -0.01, +0.05, +0.06, -0.005 and -0.05μΩcm/K^2 respectively for transition metal impurities. This T^2 law of resistivity in α-Mn alloys was discussed as the effect of spin fluctuations.
