Some properties of the Hf-X (X-transition metal) systems obtained by x-ray diffraction, hyperfine interaction measurements by time differential perturbed angular correlations of gamma rays (TDPAC), and Faraday method magnetic susceptibility chi measurements, are investigated. Special attention is paid to the influence of the ordering of the X ions microstructure and their arrangement in the crystal lattice, on the magnetic properties of the Hf-X systems. Its shown up that X ions in the systems with different crystal structures (Ti2Ni, MgCu2, quasicrystalline) form almost identical, close-packed tetrahedral microstructures, but that their arrangement in the crystal lattice is essentially different. Obtained results suggest that besides the mentioned arrangement of the X-ions microstructures, magnitude of Hf-X e.g. X-X coupling substantially influence the magnetic properties of the systems.
