Study of magnetic properties of a nano-graphene monolayer within Ising ferromagnetic model with mixed spins

The magnetic properties of nano-graphene monolayer were investigated in the framework of Ising ferromagnetic model with mixed spins by means of Monte Carlo technique based on Metropolis algorithm. A transition between ferromagnetic and paramagnetic phases of the monolayer was established. This makes such type of nanosystem promising for spintronics and sensor applications (as magnetic field sensors). Near absolute zero temperature a magnetic hysteresis was obtained, that strongly depends on the values of the interaction constant and temperature. Obtained results agree with available theoretical and experimental works of other authors.
