✦ Synopsis

The finite temperature Lanczos method is used to study a Kondo lattice-type model with neglected charge fluctuations. We investigate small two-dimensional clusters for which thermodynamic quantities and correlation functions are calculated. They are used to construct the phase diagram for the finite size clusters. The correspondence to Doniach's phase diagram is discussed.
