## Abstract Superparamagnetic nanoparticles of magnetite (Fe~3~O~4~) 2 nm in size were produced by a co‐precipitation method. Superparamagnetic resonance (SPR) spectra at room temperature show a broad line with a Landé __g__ ‐factor, __g__ ~eff~ ≈ 2. It was observed that, as the temperature decreas
