Ferromagnetism of the 1-D Kondo Lattice Model: A Quantum Monte Carlo Study

Abstract

The one dimensional Kondo lattice model is investigated using Quantum Monte Carlo and transfer matrix techniques. In the strong coupling region ferromagnetic ordering is found even at large band fillings. In the weak coupling region the system shows an RKKY like behavior.Comment: 9 pages 5 Postscript figures and the dvi and Postscript file of the paper are available by anonymous ftp from maggia.ethz.ch (directory: /reports/92-10
