Soft magnetic materials analysis

APT cluster analysis
Cluster analysis in nanocrystalline soft magnetic materials

Nanocrystalline soft magnetic materials were investigated using Transmission Electron Microscopy and Atom Probe Tomography. A 2nm slice of a 3D atom map shows Cu clusters located at α-Fenanocrystal grains/amorphous interfaces, suggesting that they are in direct contact with α-Fe nanocrystals, indicating that they have served as nuclei for the α-Fe nanocrystal grains.
