Effective-field theory and Monte Carlo study of a layered mixed spin-1 and spin-2 Ising system on honeycomb lattice

Magnetization, compensation point, phase diagram, internal energy and specific heat of layered Ising system consisting of mixed spin-1 and spin-2 ferrimagnetic honeycomb lattice layers are examined by the use of the effective-field theory with correlations and Monte Carlo simulation. In particular,...

Beschreibung
Zusammenfassung:	Magnetization, compensation point, phase diagram, internal energy and specific heat of layered Ising system consisting of mixed spin-1 and spin-2 ferrimagnetic honeycomb lattice layers are examined by the use of the effective-field theory with correlations and Monte Carlo simulation. In particular, the results obtained by the two methods have been compared in detail.
