Structural, electronic and magnetic properties of monolayer and bilayer Fe on W(001), denoted by 1Fe/W(001), and 2Fe/W(001), and oxygen on 2Fe/W(001) have been calculated using the full potential linearized augmented plane wave method. The ferromagnetism of the Fe monolayer is found to be removed by the W(001) substrate (even as a metastable state) for the monolayer Fe/W(001) system; the AFM coupling becomes the ground state. Interestingly, an additional Fe overlayer can activate the ferromagnetism of the 'dead' Fe layer-which indicates the sensitivity of the magnetism to the overlayer thickness for Fe/W(001) especially around monolayer coverages.
