Предметные рубрики: STRONG MAGNETIC-FIELD DOPED MANGANITES MAGNETORESISTANCE Bi2O3 Аннотация: The Bi2Sn2O7 compound existing simultaneously in two polymorphic modifications, namely, orthorhombic and cubic, has been synthesized for the first time by solid-phase synthesis. The dielectric and electrical properties of the compound have been studied in the temperature range 100 K ˂ T ˂ 500 K. Anomalies in the temperature dependences of the electrical resistivity and the permittivity (imaginary and real parts) have been found at both low and high temperatures. These features are explained in terms of the model of martensitic phase transitions.
