Description In this paper, we present a new method along the spirit of the constant coupling (CC) method for a pair, but now extended to a cluster of spins. We shall call this the constant coupling cluster (CCC) method. It is known that the CC approximation can be obtained as an approximation from the cluster expansion method. This gives us some justification for the use of this approximation. We present a comparative study of the present CCC method with the Bethe-Peierls-Weiss (BPW) and CC method. We find that it does not have the defects of the BPW method nor does it have the defects of the CC method and yet it is easily amenable for applications to complicated magnetic structures, which require multisublattice description.
