✦ Synopsis

A decorated transverse Ising model on regular planar lattices is studied by the use of a generalized decoration-iteration transformation. The exact mapping relations between the singly decorated transverse Ising model and undecorated Ising Ž model without transverse field are derived. On basis of this mapping, the phase diagrams in the case of S s 1r2 S B B

. denotes the spin of a decorating atom are obtained and discussed.

The generalized mapping transformation technique is used to obtain the exact solution for the mixed spin-1 2 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 calcula
