“…2 (b). It shows an asymmetric peak typically found in FeN films and the absence of sextet confirms B hf = 0 T. This peak has been fitted using a number of combinations of singlet (S) or doublet (D) such as: (i) two S [20,32,34,45] (ii) one S and one D [45,46,79] (iii) two S and one D [25]. In all these studies the component S with isomer shift (IS) ≈ 0 mm/s has always been assigned to Fe coordinated to four N neighbors as in ZB-type FeN.…”

We studied the structural and magnetic properties of in-situ grown iron mononitride (FeN) thin films. Initial stages of film growth were trapped utilizing synchrotron based soft x-ray absorption near edge spectroscopy (XANES) at the N K-edge and nuclear resonant scattering (NRS). Films were grown using dcmagnetron sputtering, separately at the experimental stations of SXAS beamline (BL01, Indus 2) and NRS beamline (P01, Petra III). It was found that the initial stages of film growth differs from the bulk of it. Ultrathin FeN films, exhibited larger energy separation between the t 2g and e g features and an intense e g feature in the N K-edge pattern. This indicates that a structural transition is taking place from the rock-salt (RS)-type FeN to zinc-blende (ZB)-type FeN when the thickness of films increases beyond 5 nm. The behavior of such N K-edge features correlates very well with the emergence of a magnetic component appearing in the NRS pattern at 100 K in ultrathin FeN films. Combining the in-situ XANES and NRS measurements, it appears that initial FeN layers grow in a RS-type structure having a magnetic ground state. Subsequently, the structure changes to ZB-type which is known to be non-magnetic. Observed results help in resolving the long standing debate about the structure and the magnetic ground state of FeN.

“…For detection of radiation the argon filled proportional counter was applied with a beryllium window of 0.3 mm thickness. The spectrum was registered with the MOSIEK-3E spectrometer in the 2 × 512 channels mode with about 10 6 pulses per channel [5][6][7]. Parameters of hyperfine spectra were determined with the Recoil [5][6][7][8] in reference to α-Fe.…”

Iron Containing Supplement Biofer Investigated by X-ray Fluorescence, Energy Dispersive X-Ray Spectroscopy and Mössbauer Spectroscopy

et al. 2015

Iron, an important microelement essential to the functioning of the body, plays a special role in the process of respiration. There are more and more new products available on the pharmaceutical market. Some of them were the subject of previous studies, especially by using the Mössbauer spectroscopy. One of the latest is Biofer. For the present tests three tablets from three different production series of Biofer were used for examination of elemental composition using the X-ray fluorescence and energy dispersive X-ray spectroscopy methods. Information about oxidation of iron contained in the tablets was obtained with by means of the Mössbauer spectroscopy.

“…For example, pulsed laser deposition [14], molecular beam epitaxy (MBE) [15][16], facing target sputtering [17][18], magnetron sputtering [19][20], ion implantation [21][22], and RF reactive sputtering [23], were used to create Fe-N films at lower temperature. Mechanical alloying, chemical reaction, and nitriding were used to produce Fe-N powders from room temperature to 700°C [24][25][26].…”
