摘要报道了CePtSi的低温热性质和输运性质的测量结果。特别令人困惑的是，观察到的比热随温度降低而显著增加，低于0.4 K，与Pt位点处的大超精细磁场相容。没有观察到表明在升高的温度下的合作相变的特征来证明这样的假设是合理的。
Abstract Measurements of low-temperature thermal and transport properties of CePtSi are reported. Particularly puzzling is the observation of a strong increase in the specific heat with decreasing temperature below 0.4 K, compatible with a large hyperfine magnetic field at the Pt sites. No features indicating a cooperative phase transition at elevated temperatures are observed to justify such an assumption.
