摘要：

We study the magnetic excitation spectrum of the two-dimensional (2D) square-lattice S = (1)/(2) Kondo lattice model at finite (hole) doping, by representing the Hamiltonian in terms of a set of local excitations. The location of the paramagnetic-antiferromagnetic phase boundary at T = 0 is determined. (C) 2002 Elsevier Science B.V. All rights reserved.
