Monte Carlo simulations of the L1₀long-range order relaxation in dimensionally reduced systems

Abstract

Abstract. Monte Carlo simulations have been performed to investigate the relaxation of the L1 0 long-range order in dimensionally reduced systems. The effect of the number of (001)-type monatomic layers and of the pair interaction energies on these kinetics has been examined. The vacancy migration energies have been deduced from the Arrhenius plots of the relaxation times. A substantial increase in the migration energy for small film thickness is observed. The results agree with previous Monte Carlo simulations and with recent experimental results in L1 0 thin films and multilayers.

Strain-Induced Microstructural and Ordering Behaviors of Epitaxial Fe38.5Pd61.5 Films Grown by Pulsed Laser Deposition

“…Nanothin films are expected to order at lower temperatures than the bulk [160] and FePd nanoparticles are known to be fully ordered by 600°C after an onset of ordering behavior around 400°C [69,161]. This same 400°C onset / 600°C completion ordering behavior has also been observed in FePd thin film studies [126,148].…”
