Topological insulators are in the focus for enhancing spin‐to‐charge conversions when in contact with ferromagnets, and to optimize the interface is demanding. In our paper published in Advanced Materials Interfaces, we present a thermal annealing process of Sb₂Te₃, which improves the chemical, structural, and magnetic properties of Fe/Sb₂Te₃ heterostructure, even if Fe is not subjected to any thermal treatment. The method could be easily extended to similar magnetic/topological-insulators heterostructures.
