Resumen:
The ferromagnetic response from Co-doped CeO2
epilayers is shown to be linked to the formation of Co metallic
nanowires (diameters in the 37 nm range) within the oxide matrix. These
results (i) illustrate the key role of the shape anisotropy of metallic
inclusions in diluted magnetic oxides (DMO), (ii) stress the importance
to monitor the out-of-plane response of DMO, and (iii) suggest that
some dilute systems previously thought to be intrinsic ferromagnet may
be reexamined.
