An attempt has been made to resolve the question of the non-observation of characteristic anomalies in the electrical resistivity ( rho ) corresponding to the Neel temperature of CrAl alloys in the intermediate concentration range. rho -T studies are reported for the first time, on single-crystal samples containing 0.23, 0.52, 1.02, 1.41, 1.91, 2.99 and 4.53 at.% Al. Anomalies in rho are observed in the region of T_N for all these alloys although the size of the anomaly is small in the case of Cr-1.91 at.% Al and Cr-2.99 at.% Al. Comments are made on the nature of the magnetic phase appearing below T_N, as a function of the rise in Al content, in the light of the infrared reflectivity data reported earlier on these samples.
