      abstract     = {The growth of a Mn submonolayer on Pt(110)-(1x2) was
                      studied by surface x-ray diffraction. At room temperature,
                      Mn fills in the empty rows of the clean substrate's missing
                      row structure. At a coverage of 0.5 ML (monolayer), a (1x2)
                      surface alloy is formed, with alternating Pt and Mn dense
                      rows. Upon annealing (or depositing at a substrate
                      temperature of about 570 K), another surface alloy forms
                      with a (2x1) symmetry. It exhibits mixed dense rows where Pt
                      and Mn sites alternate, as in bulk Pt3Mn. The top layer is
                      corrugated for both the (1x2) and (2x1) surfaces, with Mn
                      lying 0.19 +/- 0.03 and 0.16 +/- 0.02 A above the Pt site,
                      respectively. A Pt3Mn-like slab forms when annealing a
                      3-ML-thick Mn film. The observed symmetries are at variance
                      with the NiMn and CuMn surfaces where c(2x2) arrangements
                      were found. Theoretical calculations were performed for
                      (1x2), c(2x2), and (2x1) PtMn two-dimensional (2D) alloys on
                      Pt(110). Among them, the latter was found to be the ground
                      state. Both the (1x2) and (2x1) surface alloys form
                      antiferromagnetic (AF) Mn chains running in the [1 (1) over
                      bar0] and [001] directions, respectively. The ordering
                      within the surface layer switches to ferromagnetic (F) for a
                      5-ML-thick Pt3Mn(110) film albeit with a surface structure
                      quite identical to the (2x1) 2D case. The magnetic moment
                      per Mn atom at the surface is close to 4 mu(B), in all
                      cases, among the largest values ever found in similar
                      metal-Mn surface alloys: it is directly related to the
                      surface corrugation and to the Mn volume as already observed
                      for other Mn-based surface alloys. The magnetic order, F or
                      AF, is strongly influenced by the local chemical environment
                      of the Mn sites.},
