Nanosized iron borate particles have been fabricated by mechanical grinding of FeBO3 single crystals. The phase and chemical composition of the samples have been studied by electron diffraction and X-ray energy dispersive analysis. The morphology of

Iron borate FeBO3 crystals are annealed in neutral, oxidizing, and reducing gas media on a specially designed setup. The effect of the chemical medium and annealing modes on the surface morphology and phase composition of the samples is established.

The effect oxidizing annealing has on the electrical properties of nominally pure congruently grown LiNbO3 crystals is investigated via impedance spectroscopy. A set of samples is preliminarily reduced in saturated D2O or H2O vapor. It is shown that

A comparative analysis of the Czjzek's and Maurer's models of the joint distribution density of NMR quadrupole parameters has been carried out in view of their application to account for spectra broadening induced by local disorder in crystals. As an

Monocrystals of Iron Borate, doped by nickel, FeBO3:Ni, have some extraordinary peculiarities. Domain structure of such crystals at room temperature is analogous to that of pure FeBO3 crystals. At temperature lower than 130 K, stripe domain structure

Iron borate crystals (FeBO 3 ) were flux grown at the Physical Institute (Prague) and at Simferopol State University. During the crystal growth procedure the temperature regime was held constant to 0.1°C accuracy. Crystals were investigated with the
