In recent years, there has been a surge of interest in expanding from two (2D) to three dimensional (3D) magnetic systems. This extra dimension brings new magnetic textures, which promise applications in information storage and processing. The experimental detection and 3D visualization of nanometric magnetic textures has been made possible by the development of 3D X-ray magnetic tomography. Here we have combined 3D soft X-ray magnetic imaging with the application of in situ magnetic fields, allowing us to draw a connection between the motion of 2D topological defects in magnetic thin films, and their underlying 3D magnetic structure. These advances establish the necessary capabilities for the study of the behavior of topological textures in 3D, opening the door to insights into the field-driven behavior of buried three-dimensional magnetic textures.
