[Wien] Optical graph of spin polarized system

[Peter Blaha]

The imag part of epsilon can be plotted separately for spin-up/dn, but 
the real part, coming from a Kramers-Kronig relation is defined only for 
the total.
With unpolarized light you can measure anyway only the total absorption.

For "magneto-optical" effects, you need to consider also spin-orbit 
coupling.
