Computer simulation of bilayer structures with dipolar interlayer interaction was performed. Equilibrium properties were considered for systems with various thicknesses of magnetic layers and distances between the layers. Non-equilibrium behavior was simulated for high-and low-temperature initial states.
Monte Carlo simulation was conducted for bilayer magnetic structures with dipolar interlayer interaction in an external magnetic field. Specific hysteresis loops were obtained for the system. Non-equilibrium relaxation of the autocorrelation function was considered with the high-and low-temperature initial states
The Monte-Carlo study deals with ultrathin magnetic films critical behavior. Uniaxial anisotropy, long-range dipolar interactions and external magnetic field competition effects on phase transition, domain structure and system properties were investigated. Striped spin configurations are demonstrated for system with strong dipolar interaction. The effective antiferromagnetic character of dipolar interaction is observed in bilayer structure. Memory effects in non-equilibrium critical time relaxation of magnetization and autocorrelation function are investigated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
