Magnetic Properties Of Single-Walled Carbon Nanotube With Mixed Spins: Monte Carlo Study

Single-walled, armchair type carbon nanotube with mixed spins was investigated within the framework of Ising-like ferromagnetic model, by means of Monte Carlo technique based on the metropolis algorithm. According to this approach the influence of the size effect on the nanosystem behavior was investigated. The critical point of the system was obtained. The influence of the external magnetic field on the system parameters was studied. The interaction constant between nearest neighbor nodes and the temperature are the two major factors that influence the type of phase transitions in the considered nanosystem. The perspective of possible application of such carbon nanotubes in spintronics was shown.
