Effect of the crystal structure defectiveness on magnetic state of sodium-doped lanthanum manganites

Tovstolytkin, A.I.; Pogorily, A.N.; Kotov, V.V.; Belous, A.G.; V’yunov, O.I. (Functional Materials, 2004)

Structural, electric, magnetoresistive, and resonance properties of La₁-xNaxMnO₃₊y samples synthesized by solid phase reactions have been studied. It is shown that the valence state of manganese remains essentially unchanged ...
Temperature trends of the permittivity in complex oxides of rare-earth elements with perovskite-type structure

Belous, A.G.; Ovchar, O.V.; Mischuk, D.O. (Condensed Matter Physics, 2003)

Ceramic materials based on complex oxides with both the perovskite structure (Ln₂/₃Nb₂O₆) and the structure of tetragonal tungsten bronze (Ba₆−xLn₈+₂x/₃Ti₁₈O₅₄) have been investigated over a wide frequency and temperature ...
The effect of isovalent substitutions and dopants of 3d-metals on the properties of ferroelectricssemiconductors

V'yunov, O.I.; Kovalenko, L.L.; Belous, A.G. (Condensed Matter Physics, 2003)

Electrophysical properties and microstructure of PTCR ceramics of the system (Ba,Ca,Sr,Y)TiO3 + y%Mn have been investigated. It has been shown that manganese ions increase the potential barrier at grain boundaries and form ...
