A microwave 2.45 GHz source was operated at 430 W. The reaction was performed in a quartz tube passing through the microwave waveguide. The in-situ passivation using air was applied after synthesis. The powder was characterised by TEM, XRD, and M\u00F6ssbauer spectroscopy. According to our TEM investigation, the produced passivated powder included aggregated core-shell nanoparticles. The cores consist of \u03B1-Fe and the shell is supposed to be iron oxide (indicated by TEM). The presence of \u03B1-Fe and iron oxides was confirmed by XRD and M\u00F6ssbauer spectroscopy. The mean coherence domain size of \u03B1-Fe cores was estimated to be 30 nm. The synthesized nanopowder exhibits ferromagnetic behaviour."@en . . "2005-11-08+01:00"^^ . .
