The task of the project is to study the structural and magnetic properties of coordination nanoparticles (CNPS’s) based on Prussian Blue analogues complexes, CsNiCr and CsCoFe, and core-shell type CNP’s. These novel systems open new possibilities for the design of molecule-based switchable objects where magnetism may be controlled or tuned by an external perturbation (light, temperature, field, etc.). The project aims at understanding the magnetic conformations of the nanoparticles and their eventual interactions. The methods of investigation will include small-angle scattering (SANS, SAXS), neutron diffraction, Inelastic Neutron Scattering (INS), and magnetometry (DC/AC) using SQUID and PPMS. Part of the work will also consists in developing new setups for in situ low-temperature photomagnetic studies under magnetic fields. Neutron experiments will be carried out at the LLB (CEA Saclay, south of Paris) and/or at the Institute Laue-Langevin (Grenoble).
