• Magnetoresistive contribution to the residual resistivity of polycrystalline pure irons, having the electrical resistivity ratios RRR=ρ(295°K)/ρ_0(4.2°K) from 35 to 400, has been measured at 4.2°K in longitudinal magnetic fields up to 5.5 KOe. Analysis of the relation between the resistivities of ρ(B=0, 4.2°K) extrapolated to B=0 and ρ_0(H=0, 4.2°K) at H=0 indicates that the electrical resistivity measured at H=0 contains magnetoresistive contribution of the order of 38%-84% for RRR=35-400 and depends upon the concentration of impurities. The magnitude of the maximum magnetoresistivity ρ_<mag>=(4.2°K)=|ρ_0-ρ_<imp>(B=0, 4.2°K)| was approximately found to have a value of 0.02μΩ cm for iron at 4.2°K.
