The electronic structures and magnetism of an Fe chain along the [110] direction on Cu(001) (Fe[110] chain) were investigated by using the all‐electron full‐potential linearized augmented plane‐wave method within the generalized gradient approximation. The calculated results showed that the Fe magnetic moment of the Fe[110] chain is 2.99 μ B /atom. This value is much larger than that (2.22 μ B /atom) of the bcc bulk iron, but the value is smaller than that (3.20 μ B /atom) of the free standing Fe chain and that (3.11 μ B /atom) of the Fe chain along the [010] direction on Cu(001). Large enhancement of the Fe magnetic moment of the Fe[110] chain is explained by the localization of the Fe d‐band due to the reduced coordination number which is confirmed from the calculated spin‐polarized layer‐projected density of states.
