摘要：

Hall coefficients of single crystal CeNiSn exhibit huge positive peaks near 9 K and steeply decrease almost as ln T to the large negative value - 0.1 cm3/C at 1.3 K. Both the semiconductor-like behavior in the resistivity below 6 K and the positive peak in rho(a)(T) near 11.4 K disappear only when a magnetic field higher than 12 T is applied along the a-axis. These results indicate that a coherence pseudogap opens below 6 K in the quasiparticle density of states resulting from the development of an antiferromagnetic correlation.
