About the method

Mössbauer spectroscopy of 57Fe allows atomic-level characterization of the state of nucleus and the effect of environment on it at the atomic level. Recently, our main interest concentrates in physical and chemical behaviour of nanometric-scale particles of iron oxides and of iron-based alloys. In addition to Mössbauer spectroscopy (in transmission mode, conversion electron and conversion X-ray MS), we combine techniques of structure analysis (X-ray flourescence, X-ray diffraction, electron microscopy) with studies of magnetic properties (SQUID), distribution of hyperfine fields from nuclear magnetic resonance and, where feasible, also with DFT calculations.

Typical application of these techniques is to:

  • determine phase composition os samples containing various compounds of iron or iron-based alloys (mineralogy, geology, metalurgy, engineering, chemistry)
  • identify corrosion products
  • characterize surface layer
  • study structural defects induced by radiation damage
  • and others


  • powders (minimum weight ~10 mg)
  • foils (width 1-100 μm, area of few square mms)
  • supported layers
