Effective distance of a ferromagnetic trilayer Ising nanostructure with an ABA stacking sequence

“…Moreover, the magnetizations are m c1 = m c2 = m e1 = m e2 = M T = 1 at T = 0. In our previous study [47] we found that the critical phase transition of the two layer Ising nanographene occurred at T C = 2.12J/k B for d = 1. However, for the TLINS, the critical phase transition occurred at T C = 2.37J/k B for d = 1…”

“…Thus, m c1 has three nearest-neighbor central atoms (m c2 ), m c2 has one nearest-neighbor central atom (m c1 ) and two nearest-neighbor edge atoms (m e1 ), m e1 has one nearest-neighbor central atom (m c2 ) and one nearest-neighbor edge atom (m e2 ), and m e2 has two nearest-neighbor edge atoms (m e1 ). In addition, each magnetic atom in the layers has one nearest-neighbor atom, which is in the nearest-neighbor layer [47].…”

“…The theoretical results that we obtained for the TLINS agreed with the theoretical and experimental results reported for previous systems. We compared our theoretical results based on the effect of the number of layers (thickness) with those described in our previous study [47] and those in Refs. [48][49][50][51][52].…”

“…Furthermore, layer antiferromagnetic and paramagnetic insulator phases have been observed in the BHL. Recently, the magnetic properties of different graphene structures have been studied by the various theoretical methods within the Ising model [42][43][44][45][46][47].…”

Thermodynamic Properties of the Core/Shell Antiferromagnetic Ising Nanocube

“…On the other hand, the magnetic and thermodynamic properties of these NP systems have been studied by a variety of techniques, such as the mean-field theory (MFT) [13], effectivefield theory (EFT) with correlations [14][15][16][17], Green functions (GF) formalism [18], variational-cumulant expansion (VCE) [19], and Monte Carlo (MC) simulations [20][21][22]. Based on the EFT with correlations, Canko et al [23] have investigated the magnetic and the thermodynamic properties of a cylindrical spin-1 Ising nanotube, and they have also investigated the magnetic susceptibility, specific heat, internal energy, and free energy of a cylindrical mixed spin-1 2 and spin-1 Ising nanotube [24].…”
