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.
