Short-range order in face-centered cubic VCoNi alloys

Short-range ordering in face-centered-cubic Ni3AI

Ftis of fee NilAl with suppressed short-range order (SRO) were prepared by physical vapor deposition of N&Al onto room-temperature substrates. Extended electron energy-loss fine-structure spectra were obtained from both Al K and Ni h3 edges. After the samples were annealed for various times at 150 “C!, a moderate growth of SRO was observed in the first-nearest-neighbor environments of both the ...

Simulation of self-assembled nanopatterns in strained 2D alloys on the face centered cubic (111) surface.

We investigate the formation of nanostructures in 2D strained alloys on face centered cubic (111) surfaces by means of equilibrium Monte Carlo simulations. In the framework of an off-lattice model, we consider one monolayer of two bulk-immiscible adsorbates A and B with negative and positive misfit relative to the substrate, respectively. Simulations show that the adsorbates partly self-organiz...

Ferromagnetic Ground States in Face-Centered Cubic Hubbard Clusters

In this study, the ground state energies of face-centered cubic Hubbard clusters are analyzed using the Lanczos method. Examination of the ground state energy as a function of the number of particle per site n showed an energy minimum for face-centered cubic structures. This energy minimum decreased in n with increasing coulombic interaction parameter U. We found that the ground state energy ha...
