THE STRUCTURAL, IMPEDANCE AND DIELECTRIC A FERRITE CORE OF IRON MANGANITE AND ITS COMPOSITE

THE STRUCTURAL, IMPEDANCE AND DIELECTRIC A FERRITE CORE OF IRON MANGANITE ITS COMPOSITE. Samples with single-phase MnFeO3 and multiphase MnFeO3/ZnFe2O4 (30/70), MnFeO3/ZnFe2O4/LaMnO3 (30/40/30) have been successfully prepared as ferrite cores by the solid-state reaction method using high energy milling. Crystal structure, surface morphology, impedance, AC-conductivity dielectric quantities, such constant loss studied. The crystalline structures for MnFeO3, ZnFe2O4, LaMnO3 are hexagonal, cubic monoclinic, Rietveld program used XRD analysis resulted in composition fractions of single phase (31/69), (31/40/29). morphology all samples has a heterogeneous shape size low porosity. impedance is higher than sample. conductivity three same pattern, which relatively at frequencies begins to increase above 10 kHz.
