WP2: Synthesis and Characterization of tetragonal FeNiCo ternary nanoalloys
“Epitaxial-like” growth in liquid phase of L10 FeCo on L10 MPt binary nanoalloys, where M=Fe or Co. Formation of core/shell type colloids.
Description of Work: 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.
