摘要: An effective-field theory with correlations is developed for a mixed spin-1 and spin-5/2 Ising ferrimagnetic system on the honeycomb ( = 3) square 4) lattices in absence presence of longitudinal magnetic field. The ground-state phase diagram model obtained field (h) single-ion potential or crystal-field interaction (1) plane. We also investigate thermal variations sublattice magnetizations, present diagrams (1/|J|,kBT/|J|) susceptibility, internal energy specific heat are numerically examined, some interesting phenomena these quantities found due to applied Moreover, undergoes second- first-order transition; hence, gives tricritical point. exhibits reentrant behavior.
