โœฆ Synopsis

The one-dimensional Kondo lattice is diagonalized numerically. It is shown that the ground state is ferromagnetic at low densities of conduction electrons. On the other hand at half-filling the ground state is a singlet with stronq antiferromagnetic correlations which are localized spins.

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 de
