Synthesis and magnetic properties of carbon-coated FeRu, CoRu, and NiRu nanoalloys — •A.A. El-Gendy, V.O. Khavrus, S. Hampel, A. Leonhardt, R. Klingeler, and B. Büchner — Leibniz Institute for Solid State and Materials Research (IFW) Dresden, Germany

Carbon coated FeRu, CoRu and NiRu nanoalloys have been synthesised by high pressure chemical vapour deposition (HPCVD). The formation of the core-shell nanoalloys with a mean diameter around 8 nm has been confirmed by means of high resolution transmission electron microscopy imaging (HRTEM), energy dispersive X-ray (EDX) analysis, and X-ray diffraction (XRD. We show the effect of the synthesis parameters on the actual composition of the nanoalloys and on their magnetic properties and we discuss their feasibility for applications in medical hyperthermia.
