Left: angular dependence of the in-plane FMR spectra taken at RT: (a) Fe nanodots on 0.1° and 4°; (b) miscut Si(111) substrates. Right: experimental (green circles) and fitted (red 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: black lines, vicinal plane: blue lines.^{[ 67 , 69 ]}
