Abstract
Using the P-site CPA, we show that in the two-dimensional doped Ising- like Heisenberg ferromagnets the dependence of the coherent exchange c ouplings on the impurity concentration is the same as that of antiferr omagnets. The coherent magnetic fields and magnetic susceptibilities a re obtained within the framework of the 1-site CPA. The magnetic susce ptibilities obtained from the CPA are compared with the perturbative r esults in the low impurity concentration range.
