Abstract
Thermopower measurements are reported on samples containing 0.52, 1.02 and 1.41 at % Al. The commensurate-incommensurate SDW transition is resolved for the first time for Cr + 1.41 at % Al. Cr + 1.02 at % Al shows a sharp Néel transition at 188 K, and a rather broad transition between 170 K and 135 K, which may arise from inhomogeneity of the sample in the sensitive region of the magnetic triple point.
