Structure and stability of ultrathin Fe films on W(110)
The growth of one and two atomic layers of iron on a W(110) substrate was followed by low-energy electron microscopy. The near-surface structural properties of the perfectly flat pseudomorphic films were studied by quantitative low-energy electron diffraction analysis from areas of uniform thickness as well as by the density functional theory. A strong relaxation of the outermost atomic layers ...
متن کاملSpin-density wave in ultrathin Fe films on Cu(100).
For Fe films epitaxially grown on Cu(100) at 300 K, the total magnetic moment as a function of film thickness and its temperature dependence have been investigated in situ with a multitechnique approach. The results exclude the collinear type-1 antiferromagnetic configuration as the magnetic structure for face-centered-cubic Fe films on Cu(100). It is proposed that a spin-density-wave state is ...

Ultrathin Fe films on Cu~111! have been grown by pulsed-laser deposition ~PLD! whose instantaneous deposition rate is about six orders of magnitude larger than that of the conventional molecular-beam epitaxy based on thermal deposition ~TD!. Compared to the TD prepared Fe/Cu~111! films, the PLD films have a significantly improved layer-by-layer morphology and a substantially enhanced stability ...

Fe films in a coverage range of 0.4<u<4.7 ML were deposited on a Mo~110! substrate in the 300<T <700 K temperature range. It is found that growth around 300 K is mediated by the step-flow growth mechanism, in contrast with previous studies of the Fe/Mo~110! and Fe/W~110! systems, where growth at 300 K was mediated by two-dimensional island nucleation and coalescence. This difference is attribut...
