Résumé
The rational design of well‐defined core–shell gold Prussian‐blue analogous nanoparticles is presented together with an in‐depth study of their optical and magnetic properties. It is shown that both properties may be tuned by modifying various parameters. This approach constitutes a first step towards the design of Prussian‐blue analogous magnetoplasmonic heterostructures. The cover artwork was designed by Mr. S. Bertrand. More information can be found in the Full Paper by J. Long and J. Larionova et al. on page 7483.
