本文用比热测量的方法研究了磁场对CeNiSn中电子基态的影响。在高质量的单晶中，我们可以在2-25K的温度范围内观察到比热的显著场效应。基态是由近藤共振带中的赝隙态密度和费米能级上的剩余态引起塞曼分裂来讨论的。
The effect of magnetic field on the electronic ground state in CeNiSn has been investigated by means of specific-heat measurement in magnetic fields µ 0 H up to 14 T. A high-quality single crystal allows us to observe a marked field effect on specific heat in the temperature range from 2 to 25 K. The ground state is discussed in terms of a pseudo-gapped density of states in the Kondo resonance band with residual states at the Fermi level inducing the Zeeman splitting.
