The KKR-CPA has been used with success to study the physics of a variety of alloy systems, including those where disorder is only present on one sub-lattice (the 'inhomogeneous' CPA). In addition, it has been shown that the CPA can very effectively describe magnetism at finite temperature, by considering (weighted) averages taken over all possible spin orientations. This is referred to as the 'disordered local moment' (DLM) picture and can be used to describe the ferromagnetic phase transition in metals.
