Surface sulfidation of iron nanoparticles with hydrogen sulfide yields structurally well‐defined core–shell systems exhibiting an iron core and an iron sulfide shell. According to Mößbauer studies the shell′s chemical composition is best described as a mixture of Fe 1‐X S, Fe 2 S 2 , and Fe 7 S 8 . Magnetic measurements reveal the partially preserved ferromagnetic character of the core–shell particles, which is also reflected in substantial magnetic heating properties of the material. More information can be found in the Full Paper by Bruno Chaudret et al. on page 663 in Issue 7, 2018 (DOI: 10.1002/cnma.201800027).
