Magnetic defects in non‐doped and iron‐doped nanopowders of KTaO3 were studied by resonance and static magnetic measurements. The resonance spectra and hysteresis loops of KTaO3:Fe nanocrystalline powders were observed and investigated for the first time. Unlike bulk crystals, both non‐doped and doped nanopowders exhibit two types of resonance lines, paramagnetic ones from the isolated Fe3+ ions and...
Electrochemical behaviour of Ti(IV) species in the ionic liquid (IL) 1-butyl-2,3-dimethylimidazolium tetrafluoroborate (BMMImBF 4 ) was studied by means of chronopotentiometry (CP) and cyclic voltammetry (CV) in melts with different concentrations of TiF 4 (2–35mol%) within a temperature range of 65–180°C. The electrochemical reduction of Ti(IV) was suggested to proceed via the sequence...
