摘要：

Measurements of electrical and thermal transport coefficients in the antiferromagnetic alloy Cr99.94Al0.06 reveal an anomaly near the Néel temperature TN. Temperature derivatives of the electrical resistivity and thermo-power are analysed and are shown to be proportional to each other above and below TN in the reduced temperature range 6 × 10-2 ≥|t|≥ 4 × 10-4. This is consistent with the theoretical prediction of a universal critical behaviour of all transport coefficients. © 1979.
