The financial support of the Spanish MINECO MAT2014-53921-R and Aragonese DGA-IMANA E34, both cofunded by Fondo Social Europeo and European Union FEDER funds is acknowledged. T.G. acknowledges support from the National Science Foundation (NSF) DMR-0847552 and the W.M. Keck Foundation. The XMCD experiments were performed at the ID08 (now ID32) beamline of the ESRF, experiment HE2486. This is a highly collaborative research. The experiments were conceived jointly, the data was extensively debated and the paper was written by multiple iteration between all the coauthors. Samples were fabricated, characterized and prepared at UCSD (T.G. and I.K.S.). The research at UCSD was supported by the Office of Basic Energy Science, U.S. Department of Energy, BES-DMS funded by the Department of Energy's Office of Basic Energy Science, DMR under Grant No. DE FG02 87ER-45332.

Magnetic anisotropy in Fe phthalocyanine film deposited on Si(110) substrate: standing configuration
Анотація:
In this contribution we report on the structural and magnetic properties of an Fe phthalocyanine (FePc) thin film deposited on a silicon substrate. The planar FePc molecules order spontaneously in a standing configuration, i.e., with the molecular plane perpendicular to the substrate. The x-ray linear polarized absorption and x-ray magnetic circular dichroism experiments at the Fe-L2,3 edges at T = 6 K were performed, concluding that at this temperature the film displays magnetic anisotropy with the main easy axis perpendicular to the substrate. This result is explained in terms of the FePc single molecule anisotropy which has its larger moment in the molecule plane. Thus, the standing configuration in polycrystalline thin films favors statistically that, at the macroscopic array level, the magnetic easy anisotropy axis is normal to the substrate.
