Magnetic interactions in disordered perovskite PbFe_{1/2}Nb_{1/2}O_3 and related compounds. Dominance of nearest-neighbor interaction
R. O. Kuzian, I. V. Kondakova, A. -M. Dare +1
We show that the magnetism of double perovskite AFe_{1/2}M_{1/2}O_3 systems may be described by the Heisenberg model on the simple cubic lattice, where only half of sites are occup…
Time-resolved spectroscopy of exciton states in single crystals, single crystalline films and powders of YAlO_3 and YAlO_3:Ce
V. Babin, L. Grigorjeva, I. Kondakova +6
Luminescence characteristics of single crystals (SC), single crystalline films (SCF), powders and ceramics of YAlO_3 and YAlO_3:Ce have been studied at 4.2-300 K under photoexcitat…
Mechanisms of magnetoelectricity in manganese doped incipient ferroelectrics
R. O. Kuzian, V. V. Laguta, A. -M. Dare +8
We report magnetization measurements and magnetic resonance data for SrTiO3 doped by manganese. We show that the recently reported coexistent spin and dipole glass (multiglass) beh…
Analysis of the electric field gradient in the perovskites SrTiO3 and BaTiO3: density functional and model calculations
K. Koch, R. O. Kuzian, K. Koepernik +2
We analyze recent measurements [R. Blinc, V. V. Laguta, B. Zalar, M. Itoh and H. Krakauer, J. Phys. : Cond. Mat., v.20, 085204 (2008)] of the electric field gradient on the oxygen…
Electron spin resonance investigation of Mn^{2+} ions and their dynamics in manganese doped SrTiO_3
V. V. Laguta, I. V. Kondakova, I. P. Bykov +4
Using electron spin resonance, lattice position and dynamic properties of Mn2+ ions were studied in 0.5 and 2 % manganese doped SrTiO3 ceramics prepared by conventional mixed oxide…
Size effects in radiospectroscopy spectra of ferroelectric nanopowders
M. D. Glinchuk, I. V. Kondakova, A. M. Slipenyuk +4
The theoretical and experimental investigation of ferroelectric nanopowders is performed. The manifestation in radiospectroscopy spectra of size driven ferroelectric-paraelectric p…
