摘要：

Using the full potential linearized augmented plane wave method, spin and orbital magnetic moments along with the magnetocrystalline anisotropy energies (MAE) of linear shape Co nanochains consisting of two to seven atoms were explored. The MAE and orbital magnetic moments are strongly oscillatory against the size of nanochains. The magnetic circular dichroism sum rules were validated, but the relationship between MAE and the anisotropy of orbital moments was denied for these ultrasmall nanoentities due to large spin-flip contribution to MAE.
