Nanoscale Mapping of Magnetic Textures in 3D Using Vector Field Electron Tomography — •Axel Lubk^1,2 and Daniel Wolf¹ — ¹Leibniz Institute for Solid State and Materials Research, Dresden, Germany — ²Institute of Solid State and Materials Physics, TU Dresden, Germany

Vector field Electron Tomography (VFET) combines Electron Holography and Electron Tomography in the Transmission Electron Microscope (TEM) to reconstruct magnetic induction vector fields in 3D down to several nanometer resolution. In this tutorial we discuss the foundations of the technique, the practical workflow including pitfalls, and application to topical examples in nanomagnetism including domain walls in nanowires and skyrmion strings.
