Abstract
Using the full potential linearized augmented plane wave method, magnetocrystalline anisotropy energies of Co monatomic chains on top of the Cu(001) and Pt(001) substrates, as well as in the free standing cases, were investigated. For the free standing Co monatomic chain, the magnetic moment is found to align perpendicularly to the wire, whereas the magnetization is along the Co wires supported on the Cu and Pt substrates. The origin of this switch was explained in terms of changes in electronic band structures.
