Abstract
Using a tight-binding Hubbard model within the unrestricted Hartree-Fo ck approximation we study the ground state electronic and magnetic str ucture of an Ru monolayer epitaxially adsorbed on graphite, Pfandzelte r et al. (R. Pfandzelter. G. Steierl and C. Rau, Phys. Ret. Lett., 74( 1995;) 3467: G. Steierl, R. Pfandzelter and C. Rau, J. Appl. Phys., 76 (1994) 6431) have recently studied this system experimentally and they observed ferromagnetism at temperatures below 250 K. By comparison wi th an isolated Ru monolayer which has the same structure as the adlaye r we discuss the role of the graphite substrate.
