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. |
