=====Magneto-optics=====


The magneto-optical part is optional. To enable this part do the following. 

  * In the magneto-optics sheet click on "add magnetization".
  * give the magnetization direction of all layers and click on apply to all layers. This can be changed on a per layer base in the Properties dialog for each layer. 
  * In case of measurements with circular light the polarization should be set to left and right circular polarization. 
  * In the preferences menu activate the following
    * To enable full accuracy of calculation enable the Zak matrix formalism as algorithm.
    * Check which asymmetry definition for the data you want to use.
    * Treat dm and bm as magnetic contribution.
  * Load the asymmetry files of your measured data.
  * Fill the columns deltam and betam with proper values. The definition is given in the Terms and Definition document. 
  * Use the mode asymmetry.

Note that the Parrat algorithm is able to calculate magnetic contributions as an approximation. But the polarization must be set to circular light to work properly.


==Option: magneto-optics==

__no magnetization__ \\ 
The magnetic part is automatically disabled. The results are identical as to set <m>Q=delta_m +i beta_m=0</m>. 
In this case the Zak formalism will give the same result as Parratt.

__add magnetization__ \\ 
The magnetio-optical part is enabled. 

__magnetization with mag. profile__ \\ 
The magnetio-optical part is enabled and it includes the magnetic profile.
