The effect of considerable Faraday rotation (FR) and figure of merit (Q) enhancement in Bi, Gd, Al-substituted iron garnets: Bi2O3 nano-composite films produced by separate reactive ion beam sputtered Bi:YIG and Bi2O3 films was found. It reached threefold enhancement of the FR and twofold of the Q one on GGG substrates.

Nanoparticles composed of magnetic γ-Fe2O3 core and organic shell were synthesized via template synthesis in the presence of functional oligoperoxide surfactants and further graft-polymerization initiated from their surface. X-ray diffraction (XRD), transmission electron microscopy (TEM) and magnetic measurements (PPMS) were used to characterize the obtained magnetic system of core-shell nanoparticles. XRD results confirm the existence of γ-Fe2O3 phase as well as show an average diameter of nanoparticles around 10 nm. The obtained particles are superparamagnetic at the room temperature. Magnetic measurements indicate also sufficiently strong dipolar interparticle interactions at low temperatures.

Thin structure of the anode-electrolyte interface (AEI) was studied, and plausible nucleation and growth mechanisms at electron-beam physical vapor deposition (EB-PVD) were established. ZrO2 condensates with two mechanisms - planar and cellular ones like it happens at solidification from liquid phase. ZrO2 condensation on ZrO2 and NiO phases occurs with two different routes. On ZrO2 phase, layer of planar growth is formed with “defective layer by defective layer” mechanism. On NiO, the layer is cellular from the very beginning of the deposition process. The layer of planar growth is formed as “dense layer by dense layer”. Deposition affected zone (DAZ) is clearly distinguished.

High temperature neutron powder diffraction experiments were carried for a thorough detailed study of the structural evolution and phase transition of lithium niobate. Already at low temperatures part of the Li ions enter the hitherto assumed empty octahedra, their amount increasing with temperature. This explains anomalies in the thermal expansion. The phase transition from the ferroelectric to the paraelectric phase proceeds in two steps, complete disordering of Li before Nb reaches its centrosymmetric site within its octahedron. Li is further disordered within the oxygen plane pointing towards relatively strong Li-O bonds. These results settle a number of controversies found in the literature and add new aspects.

The system of the LixNa1−xTayNb1−yO3 solid solutions based on sodium niobate with oxygen-octahedral type of structure is of great interest because the changes of the components concentration and the temperature are accompanied by a variety of structural phase transitions. Particularly, the Li0.12Na0.88TayNb1−yO3 solid solution is promising as a material with high superionic conductivity. When x = 0.12 the structure orders in such a way as to make the phase transition to the superionic state possible. Besides, at temperatures 315–350 °C in the Li0.12Na0.88TayNb1−yO3 solid solution the phase transition from ferroelectric to antiferroelectric phase taking place before the superionic one can be observed. They were found at ∼ 400÷460 °C.
