Resumen:	X-ray magnetic circular dichroism (XMCD) measured at T=6 K and μ0H=5 T on the α-phase Fe-phthalocyanine (FePc) textured thin films shows that the Fe2+ ions present an unusually large, highly unquenched mL=0.53±0.04 μB orbital component, with planar anisotropy. The spin mS=0.64±0.05 μB and the intra-atomic magnetic dipolar mT components were also obtained. The mL/mS=0.83 ratio is the largest measured in 3d complexes and compounds. The origin of this unusually high orbital moment is the incompletely filled eg level lying close to the Fermi energy. This explains the unusually large and positive hyperfine field detected by Mössbauer spectroscopy in FePc. The FePc film strong planar anisotropy inferred from XMCD experiments is fully confirmed by magnetization measurements.
