Dielectric Properties of Ni-Zn Ferrites Synthesized by Citrate Gel Method

Electrical and magnetic properties of Mn-Ni-Zn ferrites processed by citrate precursor method

MnxNi0.5 _ xZn0.5Fe2O4, (x = 0.05, 0.1, 0.2, 0.3, 0.4) ferrites synthesized by the citrate precursor method are investigated in the present work. Compositional variation of AC resistivity is studied and values up to 10 times greater than those for samples prepared by the conventional ceramic method are observed. It is found that resistivity decreases with increase in Mn concentration except for...

Mg-Mn ferrites synthesized by citrate precursor method

Mixed Mg-Mn ferrites of compositions Mg0.9 Mn0.1 Inx Fe2-x O4 and Mg0.9 Mn0.1 Aly Fe2-y O4 have been synthesized by the citrate precursor technique. The X-ray diffraction patterns of the samples confirmed the formation of single-phase spinel structure. The ferrites have been investigated for their electric and dielectric properties. The dc resistivity and Curie temperature were found to be incr...

Interfacial Dielectric Losses in Co-Doped Ni-Zn Ferrites

The temperature and fresuency dependence of tg8 and E' for Nk ~Ztb ferrites was studied in the 10'lo6 Hz frequency range and 20-200°C temperrhrre tange. The experimental curves exhibit aspects very dependent of composition. To verify Ulat interfacial losses, expected to appear in this type of system are compatible with the experimental results a calculation of the dielectric permittivity and di...

Improvement of the magnetic properties for Mn–Ni–Zn ferrites by rare earth Nd3+ ion substitution

Single spinel phases of Mn0.5Ni0.1Zn0.4Nd x Fe2- x O4 ferrite samples (x = 0.0, 0.01, 0.02, 0.05, 0.075, and 0.1) have been prepared by ceramic method and the composition dependence of the physical and magnetic properties has been investigated. SEM micrographs and EDX analysis revealed that there is no considerable effect for the Nd(3+) ion substitution on the average grain size or porosity, wh...
