✦ Synopsis
The low-temperature magnetic properties of the gap-type (semiconducting) Kondo lattice compound CeNiSn and the low-carrier system (semimetailic) Yb4As 3 have been investigated by means of 119Sn NMR and 75As NQR techniques, respectively. NMR and NQR studies have shown that the magnetic correlation develops below around 0.13 and 10 K for CeNiSn and Ybgms3, respectively. In CeNiSn, alloying depresses the V-shaped pseudogap, while it stabilizes the magnetic correlation toward a static magnetic ordering. In Yb4As 3, a spatial distribution of the magnetic correlation emerges, but the magnetic ordered state has not yet been identified down to 0.45 K.
