In the present work we study the effect on structural and magnetic properties due to the introduction of Fe in Mn2Ga system. Mn0.7-xFexGa0.3 (x = 0.1 to 0.3) alloys were prepared with Ar arc-melting as base materials which were subsequently converted

Conditions determining the morphology and nanoscale magnetism of Co nanoparticles: Experimental and numerical studies

Autor: Simeonidis, K., Martinez-Boubeta, C., Iglesias, Òscar, Cabot, A., Angelakeris, M., Mourdikoudis, S., Tsiaoussis, I., Delimitis, A., Dendrinou-Samara, C., Kalogirou, O.

Co-based nanostructures ranging from core-shell to hollow nanoparticles were produced by varying the reaction time and the chemical environment during the thermal decomposition of Co2(CO)8. Both structural characterization and kinetic model simulatio

High coercivity cobalt carbide nanoparticles processed via polyol reaction: A new permanent magnet material

Autor: Harris, V. G., Chen, Y., Yang, A., Yoon, S., Chen, Z., Geiler, Anton, Chinnasamy, C. N., Lewis, L. H., Vittoria, C., Carpenter, E. E., Carroll, K. J., Goswami, R., Willard, M. A., Kurihara, L., Gjoka, M., Kalogirou, O.

Cobalt carbide nanoparticles were processed using polyol reduction chemistry that offers high product yields in a cost effective single-step process. Particles are shown to be acicular in morphology and typically assembled as clusters with room tempe
