The solid-state reaction method is used to synthesize W-type Sr hexagonal ferrites Sr0.8Pr0.2(Zn1.0−xCox)2Fe16O27 (x = 0.00, 0.15, 0.30, 0.45, 0.60, 0.75). results of XRD for the ferrites, when Co content (x) 0.00 ≤ x 0.75, exhibit that they are in single hexaferrite phase. As shown by morphological analysis, particles hexagonal-shaped platelets. saturation magnetization (Ms) and magneton numbe...

Lanthanum doped Z n 0.5 C o L a x F e 2 ? O 4 spinel ferrites were synthesized through the co-precipitation technique. To characterize structural, vibrational, electro-optical, dielectric, and thermoelectric properties, following characterization techniques X-ray diffraction (XRD), Fourier transformation infrared (FTIR) Raman spectroscopy, I–V measurement analysis, UV–vis LCR meter, Seebeck Ene...

Theeffect ofTa205additiveon the electric and magnetic properties of MnZn ferrites with fine grain size was studied Aadding small amounts ofTa205 to the MnZn ferriteincreased electric resistivity, while an excessive addition of Ta205causeddecreasein resistivity without significant grain growth. In asmall amount ofTa205 the change in the electric resistivity can be explained by ~ a ' ' substituti...
