Bt. Cong et Y. Elamraoui, DILUTED ISING SPIN-1 2 LATTICE WITH AN ARBITRARY COORDINATION-NUMBER/, Physica status solidi. b, Basic research, 197(1), 1996, pp. 145-151
A useful representation for the Callen identity in the case of spin-1/
2 is introduced by a simple technique. The phase diagrams and percolat
ion problems of the diluted Ising lattice with arbitrary coordination
number z are also discussed.
