Abstract
The monolayer of the highly ordered GdFe2 alloy was prepared on top of a W( 110) substrate and characterized by using scanning tunneling microscopy (ST M) and low energy electron diffraction (LEED). The crystallographic arrange ment of the ultrathin films does not coincide with the bulk structure (C15 Laves phase). This is due to the large misfit between the lattice constant of the Laves phase and the W(110) substrate. A structure model for the ultr athin GdFe2 films on W(110) is proposed basing on atomically resolved STM i mages and LEED studies.
