AB  - This study comprises an ab-initio computational investigation of the topological Hall effect (THE) arising from magnetic skyrmions in thin film Pd/Fe/Ir(111)[1]. The research is motivated by the significance of electrically detecting magnetic skyrmions for spintronic applications. To achieve the formation of stable magnetic skyrmions in this system, we employ non-collinear spin-density-functional theory within the Korringa-Kohn-Rostoker (KKR) Green function method. The multiple scattering problem is solved using the full-potential relativistic KKR method [2], and subsequently, the spin-transport calculations are carried out using the Boltzmann formalism [3] to find the resistivity and the topological Hall angle. We investigate the influence of the skyrmion size on the Hall angle and explore the impact of additional electron scattering, modeled as random disorder broadening, on the THE. Our findings indicate a significant correlation between the THE and the degree of disorder in a sample.We thank the ML4Q (EXC 2004/1 - 390534769) for funding.[1] N.
