We studied some magnetic behaviors of the Ising model in a triangular spin tube using the effective field theory (EFT) with correlations. We examined the effects of the exchange anisotropy $$J^{\prime} = \frac{{J_{ \bot } }}{{J_{//} }}$$ , and temper

An effective field method has been employed to study the magnetic properties of a ferrimagnetic mixed-spin Ising trilayer nanographene structure. The system is formed by alternate layers of two different spins atoms A (spin-1) and B (spin-½) arrange

A hexagonal spin nanotube is studied using the Effective Field Theory with correlations (EFT) and the differential operator technique (DOT). Each spin is connected to the nearest-neighbors through exchange couplings both along the chains (J // ) and

In this work, we aim to study both analytically and numerically the behavior of triangular spin tubes made by three chains which are connected to one another by exchange, in the presence of single-ion anisotropy. By diagonalizing the spin Hamiltonian

The magnetic behavior of the spin - ½ Ising system, consisting of a squared four-legs Nanotube connected to each other by different exchange couplings, have been studied by mean of the effective field theory (EFT). The Nano-system can be immersed in
