A nanopowder containing γ-Fe₂O₃ particles was synthesized by adding a gas mixture of H₂/Fe(CO)₅ into a microwave torch discharge at 1 bar. The presence of γ-Fe₂O₃ phase was confirmed by powder X-ray diffraction (mean crystallite size d_{XRD}=24 nm). The dominating characteristic sextets of γ-Fe₂O₃ were identified in the Mössbauer spectrum taken at 5 K. The presence of pure Fe₃O_4 in the nanopowder was excluded. The Mössbauer spectrum taken at 5 K exhibited six times larger total spectrum area than the Mössbauer spectrum taken at 293 K. Zero field cooled/field cooled curves measured down to 4 K in the magnetic field of 7.9 kA/m are reported.
