Magnetometry of the ferromagnetic monolayer Fe(110) on W(110) coated with Ag

Abstract
Magnetic moments per atom in the thermodynamically stable pseudomorphic monolayer Fe(110) on W(110), coated with Ag, were determined by magnetometry in UHV above 220 K. Extrapolation to T=0 using temperature-dependent magnetic hyperfine fields, measured by conversion electron Mössbauer spectroscopy, results in ground-state moments enhanced by (14±5)% in comparison with bulk Fe.
