WP4: Synthesis and Characterization of L1₀ MPt/L1₀ FeCo core/shell type nanoparticles, where M is Fe or Co

Liquid phase synthesis of L1₀ ordered MPt nanoparticles and complete structural, morphological, and magnetic characterization using XRD, Rietveld analysis, Mossbauer, TEM and VSM or SQUID. Utilization of the corresponded nanoparticles as nuclei centers for the growth in high boiling point organic medium, of FeCo shells with controllable thickness. Structural characterization of the FeCo shells and estimation of the overall core/shell nanoparticles magnetic properties.

The main tasks are of the WP4 are: 4.1. Synthesis of colloidal L1₀ MPt nanoalloys, 4.2. Growth of FeCo on the L1₀ MPt colloids 4.3. Structural, morphological and Magnetic Characterization of the corresponded core/shell nanoparticles.
