We investigate the effects of two different forms of defects on the half‐metallic properties of the Mn/Si digital ferromagnetic heterostructure (DFH) (PRL 96 , 027211 (2006)) using first principles algorithm based on density functional theory. The half metallicity is retained when the δ‐layer of the Mn atoms has 25% imperfection and even a vacancy. The cruci al properties of the DFH are robust against 25% defects (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
