“…The subsequent growth of Co on the Cu(1 1 0)-{2 Â 1}O surface changes the growth mode from the 3D island growth found for clean Cu(1 1 0), to 2D layer-bylayer growth of pseudomorphic Co and was shown to suppress the CO induced easy axis rotation [30][31][32][33][34][35][36]. More recently work has been done on the N terminated Cu(1 1 0) surface with a view for nanowire and nanocrystal growth [37,38].…”

“…Indeed, self‐organization of monatomic wires during deposition of Cu on Pd(110) 66, 68, 69 and Co on Pd(110) 6 has been observed. In other related systems, like Au/Ni(110) 64, Ag/Cu(110) 65, Co/Cu(110) 70, 71, formation of 2D nanoislands, elongated along the 1–10 direction, has been found in the sub‐monolayer regime. As a rule, these experimental investigations have been performed at room temperature (RT) or close to it 69.…”

Performing large-scale atomic simulations by means of kinetic Monte Carlo method we study room temperature selforganization of 3d magnetic atoms (Fe, Co) on fcc (110) surfaces (Pd(110), Cu(110)) in the sub-monolayer regime. The energetics of various diffusion processes relevant for these systems is investigated based on first principles calculations. We reveal that surface-confined atomic intermixing plays a significant role in the formation of nanostructures. Our results lead to the conclusion that the deposited species (Fe, Co) are captured into the topmost surface layer, while the ad-layer structure consists mainly of the expelled substrate atoms (Pd, Cu). Our studies shed a light on recent experimental investigations on the metal-on-metal growth on fcc (110) surfaces.

“…Due to advanced manufacturing techniques, well-characterized structures are nowadays available and intensively studied. [1][2][3][4][5] Recent studies of magnetic films patterned on the micron scale have revealed a number of novel phenomena that are not observed in the bulk materials; in particular, their magnetic properties are very different, 6,7 which makes them attractive as potentially useful for technological applications, as in high density magnetic recording. 8,9 The study of spin waves in low-dimensional systems such as ultrathin films has proved to very useful, in particular, for determining magnetic anisotropy constants, 10 using Brillouin light scattering, 11 which provides a tool for probing these magnetic excitations in ultrathin layers and also in dot-structured permalloy layers.…”

The influence of extended flat interface boundaries on the scattering and localization of spin waves in disordered quasi-two-dimensional Heisenberg ferromagnets is studied. The two ferromagnets are considered as two dissimilar semi-infinite slabs in contact, joined together at an extended flat interface between two adjacent planes. The mathematical framework of the matching method is used to analyze both the localization and the scattering phenomena on the extended flat interface boundaries in the harmonic approximation with nearest neighbor magnetic exchange interactions. The energy of spin-wave-localized modes arising from the absence of magnetic translation symmetry in the direction normal to the interface boundaries is determined. The transmission and reflection probabilities, as well as the average transmittance of magnetic excitations across the interface, are calculated in full accordance with the LandauerBüttiker description of electron transport, and numerical results are presented for the most representative sets of system parameters in a large range of scattering energies. Results show that there are several localized modes, which may be either optical or acoustical modes (depending on the system parameters), and the scattering properties of the system are a strong function of scattering energy and model parameters, which are assumed to be different at the interface compared with those of the bulk.
