Spin magnetization induced

In summary, the OP-term introduced by Brooks and coworkers has been transferred to a corresponding potential term in the Dirac equation. As it is demonstrated this approach allows to account for the enhancement of the spin-orbit induced orbital magnetic moments and related phenomena for ordered alloys as well as disordered. systems by a corresponding extension of the SPR-KKR-CPA method. 

The electric dipole moment operator is independent of spin and, in the absence of spin-orbit coupling, the spin part of the magnetic moment operator will have no influence on MCD. We shall therefore neglect the spin part of Eq. (8) until we come to spin-orbit-induced MCD in Section II.A.4. 

As described in Sections II.A. 1 and II.A.4, the numerical procedures required to calculate term parameters and C terms induced by the perturbation of the transition moment by spin-orbit coupling are nearly identical. Almost all of the comments concerning the calculation of terms made in Section III.A.1 apply equally well to the spin-orbit-induced C terms. The major difference between the two types of calculation is that the spin-orbit interaction is often significantly larger than the influence of a magnetic field. 

Two nitroxides, separated by the distance r, are coupled through space via electron-electron dipolar interactions arising from the unpaired electrons. Spin coupling induces line splitting dependent on their separation and their orientation with respect to the magnetic field according to...
