The anion sublattice is occupied only by As atoms, while the cation sublattice is occupied by Ga and Mn atoms, and also by As antisite defects. We consider only substitutional disorder on the cation sublattice which in turn is described within the coherent potential approximation (CPA) . We thus neglect local environment effects and lattice relaxations. 

In Section II, we discuss the effects of local arrangements of the electron cloud and other nuclei about a resonating nucleus in a molecule that are responsible for the effective magnetic field seen by this nucleus, and thus for its NMR absorption spectrum. Each interaction is discussed in turn, as if it were the only interaction present, the justification being that many timesthe NMR spectrum of a given nucleus appears to be the result of one or two interactions. A case in point is the NMR spectrum of a nucleus in a liquid, discussed in Section III. In this case, all information relating to anisotropy of the local environment effectively disappears, and the resulting spectrum is simply due to the isotropic portions of the chemical shift...
