Findings from Institute of Physics in the Area of Physics Condensed Matter Reported (Magnetocrystalline anisotropy energy for adatoms and monolayers on non-magnetic substrates: where does it come from?)

By a News Reporter-Staff News Editor at Physics Week -- Research findings on Physics Condensed Matter are discussed in a new report. According to news reporting from Prague, Czech Republic, by VerticalNews journalists, research stated, "The substrate contribution to the magnetic anisotropy energy (MAE) of supported nanostructures can be assessed by a site-selective manipulation of the spin-orbit coupling (SOC) and of the effective exchange field Bex. A systematic study of Co adatoms and Co monolayers on the (1?1?1) surfaces of Cu, Ag, Au, Pd and Pt is performed to study common trends in this class of materials."

The news correspondents obtained a quote from the research from the Institute of Physics, "It is found that for adatoms, the influence of the substrate SOC and Bex is relatively small (10-30% of the MAE) while for monolayers, this influence can be substantial. The influence of the substrate SOC is much more important than the influence of the substrate Bex, except for highly polarizable substrates with a strong SOC (such as Pt)."

According to the news reporters, the research concluded: "The substrate always promotes the tendency to an out-of-plane orientation of the easy magnetic axis for all the investigated systems."
