Self-Consistent Magnetic Force Microscopy Simulator Framework — •Dominik Schramm¹, Claas Abert², Jakub Jurczyk¹, and Amalio Fernández-Pacheco¹ — ¹Tu Wien — ²Universität Wien

With the advancement in 3D nanofabrication techniques such as Focused Electron Beam Induced Deposition (FEBID), manufacturing of complex magnetic nanostructures emanating more complex stray fields becomes feasible. [1] To quantify these fields, the development of a modified Vector- Magnetic Force Microscope (MFM), resolving all three spatial components of the stray field while still maintaining industrial feasibility, is targeted.

To design an optimized MFM tip, the micromagnetic simulation framework Neuralmag is leveraged to simulate an MFM signal. The simulator allows us to self-consistently study the impact of tip geometry, inclination angle, magnetic state as well as additional oscillatory modes not only on the output, but also on the magnetic states of tip and sample themselves. Furthermore, the simulator is employed to simulate MFM along a topographically non-trivial sample surface.
