The magnetoresistance due to electron-spin scattering in antiferromagnetic metals is obtained in the low-temperature region to the order of J2 assuming that the s-d interaction J is small, i.e., TN ≫T ≫J. Compared with the results in the simple molecular field approximation, the magnetoresistance shows a large increase at the antiferro-paramagnetic transition point Hc2.
