+ | =====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 < | ||
+ | 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. | ||
