(a) Schematic configuration of the sample; (b) the coordinate system used in our FMR measurements and data analysis, dot arrows: the unit vectors and ; (c) the STM images and LEED patterns of iron silicide phases obtained at annealing temperature for 10 min after 1.5 ML Fe deposited on 4° vicinal Si(111) surface; (d) 45 ML Fe on .
Left: The angular dependence of the in-plane ESR spectra taken at RT. Right: Experimental (circles) and fitting (line) curves of the relations between the resonance field and the rotated angle for in plane configurations, the calculated curve without the effect of uniaxial magnetic anisotropy for flat (111) plane: empty blocks, vicinal plane: empty triangles.
