Abstract
This work has consisted on processing and analysing synchrotron-based magnetic Transmission X-ray Microscopy images to obtain the internal magnetic spin texture in individual nanoflowers (NF) of about 200 nm in average size. By extracting 2D maps of the internal configuration of the magnetic moments of the cores within each NF for several tens of NF, it has been possible to visualise these different internal spin textures, all of them having in common a total magnetization close to zero. Those have been compared with previous studies, and are in agreement with prior OOMMF simulations. Due to the great variety of these configurations, a categorisation of NF subfamilies has been developed. An analysis of how the individual configurations are affected by the distance between NF has also been studied.
