WebThe term spin-orbit interaction (SOI) is known from quantum physics, where it describes the coupling between the spin and orbital angular momentum (AM) of electrons or other quantum particles [1]. The SOI is usually interpreted as an electromagnetic interaction of the moving magnetic moment of the electron with an external electric field. WebOrbital angular momentum is not a good quantum number, but depending on symmetry of lattice site, ground state may still have orbital degeneracy.Ion will have local magnetic moment which is a combination of spin and orbital angular momentum, g-factor may be far from 2, and may be strongly anisotropic. (We still describe the ground state degeneracy
