| 1 | High dielectric permittivity in AFe1/2 B1/2 O3 non ferroelectric perovskite ceramics (A=Ba,Sr,Ca; B =Nb,Ta,Sb)显示文摘 | I.P.Raevski S A Prosandeev A S Bogatin | | 0，，07： | 1 |
| 2 | Mossbauer and magnetization studies of magnetic phase transitions in 0.5BiFeO_(3)-0.5NaNbO_(3)and 0.5LaFeO_(3)-0.5NaNbO_(3)solid solutions显示文摘0.5AFeO_(3)-0.5NaNbO_(3)(A=Bi,La)solid solution compositions were prepared using a solid phase reaction route from high-purity starting oxides.Mossbauer studies have shown that while for 0.5BiFeO_(3)-0.5NaNbO_(3)the magnetic phase transition temperature T_(M) value is about 150 K,for 0.5LaFeO_(3)-0.5NaNbO_(3),it is only≈25 K.This dramatic difference in T_(M) values seems to be due to additional contribution of the magnetic superexchange between Fe^(3+)ions via the empty 6p-states of Bi^(3+)ions to the overall superexchange. | S.I.Raevskaya S.P.Kubrin Jian Zhuang I.P.Raevski M.A.Malitskaya I.N.Zakharchenko M.S.Panchelyuga V.V.Titov | 2020 | Journal of Advanced Dielectrics2020，10，1： | 0 |
| 3 | Chemical ordering and magnetic phase transitions in multiferroic BiFeO_(3)-AFe_(1/2)Sb_(1/2)O_(3)(A-Pb,Sr)solid solutions fabricated by a high-pressure显示文摘synthesisCeramic samples of BiFeO_(3)-based perovskite solid solutions with the highly ordered complex perovskites PbFe_(1/2)Sb_(1/2)O_(3)(PFS)and SrFe_(1/2)Sb_(1/2)O_(3)(SFS)were obtained using high-pressure synthesis at 4-6 GPa.Mössbauer studies revealed that BiFeO_(3)-SFS compositions are characterized by a larger compositional inhomogeneity as compared to BiFeO_(3)-PFS ones.In line with this result,concentration dependence of the magnetic phase transition temperature TN for BiFeO_(3)-SFS compositions is close to the TN(x)dependence for BiFeO_(3)solid solution with disordered perovskite PbFe_(1/2)Nb_(1/2)O_(3)(PFN).In contrast to this TN(x)dependence for BiFeO_(3)-PFS compositions nicely follows the theoretical TN(x)dependence calculated for the case of the ordered distribution of Fe3+and non-magnetic Sb^(5)+ions in the lattice(chemical ordering). | S.I.Raevskaya N.M.Olekhnovich A.V.Pushkarev Y.V.Radyush S.P.Kubrin V.V.Titov E.A.Artseva I.P.Raevski I.N.Zakharchenko C-C.Chou M.A.Malitskaya | 2022 | Journal of Advanced Dielectrics2022，12，1： | 0 |
| 4 | Photovoltaic and photoelectric response of Sn_(2)P_(2)S_(6) ferroelectric films显示文摘In the present work,the comparative study of the electric response of Sn_(2)P_(2)S_(6) films to the visible light action was carried out without and under external electric field.The light flux modulated by a chopper induces the integral response comprising time-dependent photoelectric and photovoltaic components.It was shown that spontaneous polarization influences the electric response characteristics. | A.V.Solnyshkin I.L.Kislovay A.N.Belov V.I.Shevyakov D.A.Kiselev I.P.Raevski D.N.Sandjiev S.I.Raevskaya | 2019 | Journal of Advanced Dielectrics2019，9，1： | 0 |
