Abstract

Abstract : Fine metal cobalt (Co) nanofoam was prepared via simple thermal decomposition of amorphous non‐stoichiometric Co glycerolate under 50 vol% H2 /50 vol% N2 atmosphere at 450°C. The nanofoam was characterised by X‐ray diffraction, scanning electron microscope/energy dispersive spectroscopy and its magnetic properties were investigated by SQUID magnetometer. This magnetic nanofoam consisted of slightly sintered Co nanocrystals; their average size was 30 nm.
