Makoed, I. I.; Liedienov, N. A.; Pashchenko, A. V.; Levchenko, G. G.; Tatarchuk, D. D.; Didenko, Y. V.; Amirov, A. A.; Rimski, G. S.; Yanushkevich, K. I. (Elsevier B.V, 2020)

The effect of co-doping on the structural and dielectric properties of the La0.50R0.50FeO3 orthoferrites for a full number of substitutions (R ј CeeLu) has been experimentally and theoretically studied using X-ray diffraction, ...

Weak ferromagnetism in La-doped BiFeO3 multiferroics thin films

Lazenka, V. V.; Ravinski, A. F.; Makoed, I. I.; Vanachen, J.; Zhang, G .; Moshchalkov, V. V. (American Institute of Physics, 2012)

Bi1xLaxFeO3 thin films (x ¼ 0.0, 0.3, 0.5) were grown on glass substrates by thermal physical vapor deposition. The monoclinically distorted crystal structure of the films was revealed by x-ray diffraction at room ...

The structural and dielectric properties of Bi0.80Gd0.20–xLa x FeO3 (x = 0–0.20) samples are studied by means of X-ray diffraction and dielectric spectroscopy. Room-temperature dielectric functions are examined experimentally ...

Dielectric Properties of Spinel, Garnet and Perovskite Oxides

Danil’kevich, M. I.; Makoed, I. I. (John Wiley & Sons, Incorporated, 2000)

We suggest a definition of the effective ionic charges q*i of different pairs of ions connected in tetrahedral, octahedral and dodecahedral polyhedra in such oxide crystals as spinels, garnets and perovskites. The electronic ...
