Enhancement of the Magnetic Properties for Co-Mn-Zn Ferrites

Aluminum substituted cobalt manganese zinc ferrite nanoparticles Co0.425Mn0.425Zn0.150AlxFe2-xO4 (from x= 0.0 to 0.15 with step 0.025) have been synthesized by chemical co-precipitation route. X-ray diffraction (XRD) and infrared spectroscopy (FTIR) revealed that the obtained powders have a single phase of cubic spinel structure. The crystallite sizes calculated from XRD data have been confirme...

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...

Enhancement of Néel temperature and electrical resistivity of Mn–Ni–Zn ferrites by Gd3+ substitution

Structural, magnetic, and dielectric properties of various Mn0.5Ni0.1Zn0.4Fe2−xGdxO4 sintered at 1200 ◦C were investigated thoroughly. The samples were synthesized by standard solid state reaction technique. The crystal structure was characterized by X-ray diffraction (XRD), which has confirmed the formation of single phase spinel structure. Bulk density, average grain size and initial permeabi...

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...
