Resistance anomaly near the localized-delocalized crossover point in the CeSi/sub x/ system

· Phys. Rev. B: Condens. Matter; (United States)
Anomalies in the temperature dependence of the electrical resistivity have been observed in the CeSi/sub x/ series of alloys near x = 1.855. The resistivity versus composition behavior over a 0.2 at. % composition range looks like a delta function with a decrease of about 1 order of magnitude in the resistivity on either side of the peak at CeSi/sub 1.855/, which is near the localized-delocalized crossover point. The large change in resistivity on heating or cooling apparently is due to crack formation upon cooling between 150 and 50 K, and also to crack opening or closing above and below this temperature range.
