Ab initio calculations of magnetic structure and lattice dynamics of Fe/Pt multilayers

Jochym, P. T.; Parlinski, K.; Oleś, A. M. - In: The European Physical Journal B - Condensed Matter and … 61 (2008) 2, pp. 173-179

The magnetization distribution, its energetic characterization by the interlayer coupling constants and lattice dynamics of (001)-oriented Fe/Pt multilayers are investigated using density functional theory combined with the direct method to determine phonon frequencies. It is found that...

Structural and magnetic properties of polymerized C<Subscript>60</Subscript> with Fe

Talyzin, A.; Dzwilewski, A.; Dubrovinsky, L.; Setzer, A.; … - In: The European Physical Journal B - Condensed Matter and … 55 (2007) 1, pp. 57-62

We provide evidence that high-pressure high-temperature (2.5 GPa and 1040 K) treatment of mixtures of iron with fullerene powders leads to the complete transformation of iron into iron carbide Fe<Subscript>3</Subscript>C. The comparison of the magnetic properties (Curie temperature and magnetic moment) of the here...</subscript>

Effect on alloying at the Fe/Ni(001) interfaces on the interlayer exchange coupling

Hadj-Larbi, A.; Ziane, A.; Bouarab, S.; Demangeat, C. - In: The European Physical Journal B - Condensed Matter and … 53 (2006) 1, pp. 29-34

We investigate the stability of various ordered FeNi alloys at the interfaces of Fe/Ni superlattices by using ab initio density functional calculation. We consider an Fe<Subscript>0.5</Subscript>Ni<Subscript>0.5</Subscript> ordered alloy of one or two monolayers thick at different positions beyond the interface and the possibility of an...</subscript></subscript>
