• combined approach of X-ray magnetic circular dichroism (XMCD), reflection high energy electron diffraction (RHEED) and scanning tunneling microscopy (STM) to shed light on the complex and size-dependent relation between magnetic properties, crystallographic structure, orientation and morphology. In

• scaled by a factor of 50. The low magnitude of the Fe signal relative to that of the Ni spectra reflects a well diluted deposit with about 200 particles per μm2 on the surface [38]. At this density, interactions between the particles can be neglected. Figure 2c and Figure 2d show magnetic dichroism

• α-Fe NPs with diameters down to 2 nm show an enhancement of the hyperfine field BHyp, indicative of enhanced µFe [10][11][12]. Recent careful measurements, by X-ray magnetic circular dichroism (XMCD) [13][14][15][16], consistently indicate an increase in the ratio of the orbital magnetic moment over
