Supported Sm–Co nanoparticles have been synthesized by short pulse electrodeposition using aqueous solutions containing glycine as complexant and buffering agent. Nanoparticle composition is a function of pulse amplitude and pulse duration. Short pulses in particular minimize oxygen incorporation, down to 3at%. X-ray photoelectron spectroscopy and X-ray diffraction data support the hypothesis that metallic alloys have indeed been obtained by this technique, along with mixed oxides of the metals. In-plane coercivities of up to 5.3kOe have been achieved in as-plated nanoparticle assemblies when the relative Sm content was about 20at% and particle size around 80nm. These Sm–Co nanoparticles hold the promise to be a practical and inexpensive material for use in the synthesis of permanent magnets by powder processing.
