Abstract

Magnetic properties of AA and AB stacked bilayers were investigated by means of Monte Carlo technique based on Metropolis algorithm within Ising-like model. A higher values of blocking temperature for AB stacked bilayer was obtained, which indicates that AB nano-graphene bilayer is more energetically beneficial compared to AA stacked. Transition between ferromagnetic and paramagnetic phases of the considered types of bilayers, was established. This makes such nanosystems promising in sensor applications (magnetic field sensors) and spintronics. Hysteresis near absolute zero temperature for ferromagnetic case was obtained, the existence of which strongly depends on the values of exchange interaction and temperature. Obtained results of computer simulation agree with theoretical and experimental ones of other authors.
