 +=====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.
