The generalized mapping transformation technique is used to obtain the exact solution for the mixed spin-12 and spin-S Ising model on decorated planar lattices. The critical temperature, the magnetization, the correlation functions, the internal energy and other thermodynamic quantities are...

Magnetic properties of a mixed spin-12 and spin-32 Ising model on honeycomb lattice are investigated within the framework of an exact star-triangle mapping transformation. The particular attention is focused on the effect of uniaxial and biaxial crystal-field potentials that basically influence...

A mixed spin-12 and spin-1 transverse Ising model with two- and four-spin interactions and crystal field on the honeycomb lattice is studied using a generalized mapping transformation technique. Exact expressions for the critical temperature, the magnetization, the correlation functions, the...
