Abstract

The low-temperature magnetic properties of the gap-type (semiconducting) Kondo lattice compound CeNiSn and the low-carrier system (semimetallic) Yb₄As₃ 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 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.
