摘要
The Monte Carlo replica algorithm studies of phase transitions and critical phenomena of the layered triangular antiferromagnetic Ising model with intralayer next-nearest neighbor interactions reveal a second-order transition from ordered and disordered phases, to paramagnetic phase. The character of phase transitions is analyzed using the histogram technique and Binder cumulant method. Static critical exponents for the heat capacity alpha, susceptibility gamma, order parameter beta, correlation radius v, and the Fisher exponent ri are computed by means of the finite-size scaling theory. The second nearest neighbor interactions are shown to fail to change the universality class of the critical behavior in the 3D Ising model on a layered triangular lattice. (C) 2018 Elsevier B.V.
