摘要：

The low-temperature magnetic proper-ties of the gap-type (semiconducting) Kondo lattice compound CeNiSn and the low-carrier system (semimetallic) Yb4As3 have been investigated by means of Sn-119 NMR and As-75 NQR techniques, respectively. NMR and NOR studies have shown that the magnetic correlation develops below around 0.13 and 10 K for CeNiSn and Yb4As3, respectively. In CeNiSn, alloying depresses the V-shaped pseudogap, while it stabilizes the magnetic correlation toward a static magnetic ordering. In Yb4As3, a spatial distribution of the magnetic correlation emerges, but the magnetic ordered state has not yet been identified down to 0.45 K.
