Fe_{73.5-x}Si_{13.5}B_9Cu_1Nb_3Mn_x (x=1, 3÷15) amorphous alloys were studied by means of Mössbauer spectroscopy, as-quenched and after annealing. The basic alloys show stronger magnetic ordering for small values of x, than for larger x. The initially amorphous phase and the final nanocrystalline structure were determined with X-ray diffraction. The alloys were shown, by scanning calorimetry, to suffer different phase transformations, when heated.

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.

In this work the characteristic radiation, emitted during interaction of medium energy (200 keV) ambient heavy ions (Ar) with Fe_{4}Co_{66}Si_{12}B_{14}Nb_{1}Mo_{2}Cu_{1} (VV-6025X) amorphous alloy, was measured in grazing incident-exit angle geometry and in time sequence, in order to determine dynamics of formation of subsurface region, damaged through implantation, sputtering and interface mixing. It was shown that structure and composition of surface is unstable against heavy ions irradiation due to preferential sputtering and implantation of ions, and recoils, and that the dynamics of such modification can be monitored in-situ with particle induced X-ray emission (PIXE) method.
