Гексаферрит стронция соединение с колоссальной диэлектрической проницаемостью

Гексаферрит стронция соединение с колоссальной диэлектрической проницаемостью

Abstract

The presence of colossal dielectric constant in the low frequency region is observed in the strontium ferrite with hexagonal structure. This result can be explained in the framework of the "grain-layer" and the polarization of Maxwell Wagner in the ceramic medium. The effect of negative capacitance in ceramic strontium hexaferrite at a frequency of less than 2.10 Hz has been detected.

В феррите стронция с гексагональной структурой отмечается наличие колоссальной диэлектрической проницаемости в области низких частот. Этот результат находит объяснение в рамках модели «зерно-прослойка» и поляризации Максвелла Вагнера в керамической среде. Обнаружен эффект отрицательной емкости в керамике гексаферрита стронция при частоте меньше 10 -2 Гц.
