In this work, carbon nanoballs in spherical shape with diameter 70 ± 2 nm containing well-dispersed superparamagnetic magnetite/maghemite Fe3O4/γ-Fe2O3 nanoparticles of 5–10 nm in size were synthesised by a facile route using the radio frequency (rf) plasma in order to assist the pyrolysis of ferrocene. Ferrocene was placed in an inductively coupled rf plasma field without additional thermal heating...
