Opis:: Magnetic properties of $Fe_{3-x}Cr_{x}Al$ alloys depend strongly on the unit cell volume. Purpose of this work is to investigate the dependence of the total and local magnetic moments on the lattice constant using the self-consistent spin-polarised TB-LMTO method.

Opis:: The so-called Bayesian reasoning is applied whenever uncertainty has to be considered as serious factor in interpretation of results. The paper presents analysis of the impact of inaccurate data on the straight line and quadratic relation fittings. This type of analysis is particularly important when one tries to decide on the type of dependence. The paper also shows examples of the Maximum Entropy Methods applied to the reconstruction of the hyperfine parameters distribution from the measured Mössbauer spectra of $GaFeO_{3}$ and the electron-positron momentum distribution from the positron annihilation data of Gd.

Opis:: The influence of structural disorder and magnetism on the resistivity of the amorphous Co$\text{}_{x}$Ni$\text{}_{70-x}$Fe$\text{}_{5}$Si$\text{}_{15}$B$\text{}_{10}$ ribbons was investigated. The resistivity vs. alloy composition shows parabolic-like behaviour. In the thermal behaviour, resistivities of the samples show apparent magnetic contribution. They also exhibit minima at temperatures which can be correlated with the Curie temperatures. Above T ≥ 0.5T$\text{}_{C}$ resistivity increases linearly with increasing temperature. This effect is seemingly due to electron-phonon scattering. Obviously, the chemical and positional disorder is responsible for the major part of resistivity.

Opis:: Nuclear and magnetic properties of the $ScFe_{4}Al_{8}$ single crystal were found to exhibit unparalleled complexity of nuclear and magnetic structures. Our previous neutron measurements revealed presence of two modulation vectors, both along [ε, ε, 0], however with different critical temperatures. Recent experiments forced us to revise our knowledge of the structural ordering in the sample. So far, the crystal structure of this alloy, being of $ThMn_{12}$-type, has never been questioned.

Opis:: Multicomponent single phase alloys were synthesized according to the idea of iron-average atom system. X-ray diffraction shows formation of bcc phase and traces of unidentified phase. Mössbauer spectra indicate presence of two components with different hyperfine magnetic field distributions. The high field component corresponds to the majority ferromagnetic phase. Few per cent of iron builds low field component. The dominant effect of annealing consists in an increase of the low field component.
