A simple procedure for the production of large ferromagnetic cobalt nanoparticles
journal contribution
posted on 2023-05-20, 08:00 authored by Rebecca FullerRebecca Fuller, Goh, B-M, Koutsantonis, GA, Loedolff, MJ, Saunders, M, Woodward, RCEpsilon cobalt (ε-Co) nanoparticles in a number of octahedral morphologies have been synthesised. The particles are polycrystalline, with sizes in the order of 30 nm. Magnetic studies reveal the particles are ferromagnetic, with a room temperature saturation magnetisation of 131 emu g−1. Unlike other large cubic ε-Co syntheses, we have not added an additional co-surfactant. Instead, we have modified the heating regime and reaction agitation. This alternative method highlights the complex chemistry associated with the formation of cobalt nanoparticles by thermal decomposition.
