The short-range order in a CoPt alloy was determined at 1203 and 1423 K using neutron diffuse scattering measurements. The effective pair interactions provided by data analysis reproduce well the experimental order-disorder transition temperature in

We study the magnetic short range order (MSRO) in ${\mathrm{Fe}}_{1\ensuremath{-}x}{\mathrm{Cr}}_{x}\phantom{\rule{4pt}{0ex}}(0\ensuremath{\le}x\ensuremath{\le}0.15)$ where an inversion of atomic short range order (ASRO) occurs at ${x}_{C}=0.11(1)$.

Triple-defect formation in B2-ordered binary A-B intermetallic compounds results fromthe asymmetry between the formation energies of A- and B-antisite defects. Chemical disorderingin such systems is strictly correlated with vacancy formation, which i

Self-diffusion of component atoms and ‘order–order’ relaxations in a B2-ordering binary system AB showing a tendency for triple-defect formation were consistently simulated by means of two Monte Carlo techniques. In view of a strict correlation

Lattice-gas decomposition model for equilibrium vacancy concentration in B2-ordered triple defect A–B binary intermetallic systems previously formulated and solved within the Bragg–Williams approximation was now simulated by means of Semi-Grand C

Thermal vacancy formation correlated with atomic ordering was modelled in B2-ordering A–B binary intermetallics. Ising Hamiltonian was implemented with a specific Bragg–Williams-type thermodynamic formalism for thermal vacancy formation based on

International audience; Among nanoalloys, Co–Pt type (CoPt or FePt) supported nanostructures are very interesting systems due to the direct link between atom arrangement and magnetic behavior. In addition, these alloys become model systems in the f

“Order–order” kinetics in L10-ordered FePt nano-layers have been studied by Monte Carlo (MC) simulation implemented with Glauber dynamics and vacancy atomic-jump mechanism. In the presented preliminary approach the effects of the substrate char
