Fitting Model for Spin Excitation

In this introductory lecture Prof. Markus Ternes will outline the fundamental considerations necessary to calculate the current transport through magnetic structures in a scanning tunneling setup using well established perturbation models. He will discuss the influence of higher order scattering on the spectrum and the limitations of the perturbative approach in this respect. Using the below provided scripts Prof.Ternes will discuss how one can use the ‘Graphical User Interface’ to simulate and fit single and complex spin structures in the “zero-current” and dynamical limit.

Participants interested in this lecture should bring their own laptop with them to directly use the scripts. For this, please install beforehand Scilab_6.0.2 (available without charge for Windows, Mac, and Linux from https://www.scilab.org/).
