Specific Heat Anomalies of PtCo Alloys at Very Low Temperatures

  • Chapter
Low Temperature Physics-LT 13

Abstract

At very low temperatures the magnetic behavior of the PtCo system presents different aspects. For “high” concentrations, c≧2 at. %, magnetization measurements1 show the presence of giant moments of 3.6 µB per solute atom. For very dilute alloys, c ≃ 1 ppm, nuclear orientation measurements2 give a critical (Kondo or LSF) temperature T K ≃ 1.6°K. It is thus interesting to study the appearance of the magnetic moments on the impurities below T K for intermediate concentrations, and also the way in which they appear, smoothly or abruptly, each one carrying its maximum moment.
