CPA theory of the bond model of disordered two-dimensional Heisenberg ferromagnet
TLDR
In this article, the pair effects among bonds are included in the CPA treatment of the bond model of disordered Heisenberg ferromagnet, where all spins are equated to 1 2 but two distinct exchange integrals are distributed randomly among bonds.About:

Self-Consistent Theory of Clusters in Disordered Alloys
F. Cyrot-Lackmann,F. Ducastelle +1 more
TL;DR: In this article, a way to deal with cluster effects in disordered alloys is given through an extension of the coherent-potential-approximation theory, and an explicit expression is derived for pair effects and is shown to give the exact ${c}^{2}$ term in the lower concentration limit.

Theory of a Disordered Heisenberg Model by the Coherent Potential Approximation
TL;DR: In this paper, the averaged magnon Green function in a random Heisenberg ferromagnet which has two kinds of exchange integrals J A and J B randomly distributed is calculated by the coherent potential approximation.

Fair effects in a bond model of a disordered Heisenberg ferromagnet
TL;DR: In this paper, the authors considered a disordered Heisenberg ferromagnet with spin values equal to 1/2 but two distinct exchange integrals are distributed randomly among bonds.
