Abstract
High-accuracy measurements of the temperature derivative of the electrical resistivity (d rho /dT) and magnetic susceptibility ( chi ) are used to study the complex antiferromagnetic behaviour of dilute Cr-Al alloys (cN(c)). They also explain the reason for the apparently strong discrepancies among TN values quoted in the literature for samples with intermediate Al concentrations.
