The temperature dependences of resistance, RðTÞ, of two single-crystals La 2 CuO 4 þ d samples have been studied with the aim to detect a possible change in the RðTÞ behavior induced by paramagneticantiferromagnetic (PM-AFM) transition. One of the samples with dt0:01, was fairly homogeneous in oxygen distribution (not phase-separated) with Ne ´el temperature T N % 266 K. Conductivity of this sample has been determined by Mott's variable-range hopping below T N . The other, far less resistive, sample with d % 0:05, was inhomogeneous (phase-separated) showing both PM-AFM (T N % 205 K) and superconducting (T c % 25 K) transitions. It is found that for the homogeneous sample the resistivity decreases above T N far faster with temperature than below it (for both directions of measuring current, parallel and perpendicular to basal CuO 2 planes). A similar behavior of conductivity near PM-AFM transition is also found for the phase-separated and less resistive sample. In this case a clear kink in RðTÞ curve near T N % 205 K can be seen. Furthermore, a transition to metallic (dR=dT 4 0) behavior occurs far enough above T N . The observed behavior of the samples studied is related to increased delocalization of charge carriers above T N . This is in accordance with decrease in the AFM correlation length and corresponding enhancement of the hole mobility above T N known for low-doped lanthanum cuprates.
