    Opis:
    We propose a simple model for temperature evolution of magnetic hyperfine field distribution of spherical bcc Fe nanoparticles. We performed mean field approximation calculations of mean spin value in each spherical shell of nanoparticle. Considering magnetic hyperfine field values reported for iron thin films we predicted possible values of hyperfine fields in the internal and surface region of the particles as a function of temperature.

    Opis:
    The investigations of iron-containing phases existing in fly ashes were performed using transmission Mössbauer spectrometry. The examined samples of fly ashes were collected from different coal combustion systems, that is, stoker-fired boiler in municipal heating plant and pulverized coal boiler in power plant. Several phases are identifi ed in the samples: iron oxides, paramagnetic aluminosilicate glass with Fe3+ ions and Al2O4- -type spinel with Fe2+ ions. It was pointed out that proportions of contents of phases strongly depend not only on the combustion temperature but also on the way of ash collection.

    Opis:
    In this work, a ⁵⁷Fe conversion electron Mössbauer spectrometry and X-ray diffraction have been utilized in order to investigate the structural and magnetic order in 500 nm thick Ni-Zn ferrite films deposited on Si(100) substrate by laser ablation. Considering the contributions of the conversion electron Mössbauer subspectra corresponding to the tetrahedral (A) and octahedral (B) sites, the spinel inversion parameter in [Zn_{x}Fe_{1-x}]^{A}[Ni_{1-x}Fe_{1+x}]^{B}O₄ films has been estimated. The hyperfine field (B_{hf}) values in the investigated Ni-Zn ferrites thin films are about 5-8% smaller than those of bulk ferrites, which could be a sign of thermal magnetic relaxations due to the size effects. The distribution of hyperfine magnetic field directions was found to be affected by perpendicular anisotropy.

    Opis:
    Several samples of dusts from steel and coke plants (collected mostly with electro filters) were subjected to the investigation of content of mineral phases in their particles. Additionally, sample of bog iron ore and metallurgical slurry was studied. Next, the magnetic susceptibility of all the samples was determined, and investigations of iron-containing phases were performed using transmission Mössbauer spectrometry. The values of mass-specific magnetic susceptibility varied in a wide range: from 59 to above 7000 × 10−8 m3kg−1. The low values are determined for bog iron ore, metallurgical slurry, and coke dusts. The extremely high was obtained for metallurgical dusts. The Mössbauer spectra and X-ray diffraction patterns point to the presence of the following phases containing iron: hematite and oxidized magnetite (in coke and metallurgical dusts as well as metallurgical slurry), traces of magnetite fi ne grains fraction (in metallurgical dusts), amorphous glassy silicates with paramagnetic Fe3+ and Fe2+ ions, traces of pyrrhotite (in coke dusts), α-Fe and nonstoichiometric wüstite (in metallurgical slurry), as well as ferrihydrite nanoparticles (in bog iron ore). For individual samples of metallurgical dusts, the relative contributions of Fe2+/3+ ions in octahedral B sites and Fe2+ ions in tetrahedral A sites in magnetite spinel structure differs considerably.

    Opis:
    Magnetic and structural studies were performed on $Fe_{50}Co_{50}$ material. The samples (disk-shaped, diameter: 10 mm, thickness: 2.5 mm) were fabricated by compaction of powder under pressure of 800 MPa for 5 min at temperatures 300-600°C. The powder was obtained by milling of $Fe_{50}Co_{50}$ alloy swarfs in high-energy planetary mill. The milling time varied from 1 h to 40 h. In the course of milling process the mean size of alloy pieces was decreasing from about 0.5 mm to 0.05 mm (scanning electron microscopy), which provided more compact structure after compression. The annealing process during compaction strongly reduces a coercive field of the samples. Parameters of conversion electron Mössbauer spectra are almost the same for all samples, which points to not significant changes of atomic and magnetic order after milling and compacting.

    Opis:
    This work reports results from comparative Mossbauer studies of as-deposited and annealed Fe100.xGax (10 less - than or equal to x less - than or equal to 35) high magnetostrictive thin films of constant thickness (50 plus or minus 2 nm). Films were grown on Si(100) substrates using a co-sputtering and evaporation chamber where Fe has been sputtered and Ga was evaporated. During growth of films, a magnetic field of 65 kA/m has been applied in the plane of the film. Annealed films have been obtained by heating in vacuum for 1 h at 350 centigrade without magnetic field. After annealing, the saturation field of the Fe-Ga films has been significantly reduced. By means of the 57Fe CEMS technique the contributions from several phases have been found: Fe-Ga A2 (bcc), traces of DO3 phase, a gallium-rich disordered phase and iron oxides (both geothite and magnetite). For the sample with x = 26.5 the heat treatment reduces the DO3 phase content whereas for the film with x = 16.4 the opposite tendency has been observed. Mossbauer results were compared with XRD and MOKE findings.

    Opis:
    Phase composition and magnetization curves of the soft magnetic composites, fabricated by compaction of several kinds of powders mixed in various proportions, have been investigated by means of conversion electron Mössbauer spectroscopy and an alternating gradient force magnetometry. The results point to significant quantity of iron oxides - hematite and magnetite - at the surface of the samples. After the rubbing of thin surface layer, the relative content of oxides was distinctly reduced. Magnetic measurements revealed very similar characteristics of hysteresis curves for all the investigated materials.
