Monte Carlo investigation of phase changes and the order of transition of Ising modeled single-walled nanotube

The Monte Carlo analysis for the magnetic response of a single-walled nanotube using Metropolis and Wang-Landau algorithms is reported in present paper. architecture used study utilizes spin half Ising model with nearest neighbors interaction obtained various orderings, namely ferromagnetic, G-type anti-ferromagnetic, A-type C-type anti-ferromagnetic. It also found that phase changes from ferromagnetic/anti-ferromagnetic to paramagnetic modification system’s control parameters. transition temperatures determined strength absence field fixed inclusion external field. confirms second-order transition.
