Dc electrical resistivity was studied for zn x ni 1 x fe 2 o 4 samples with x 0 0 2 0 4 0 6 0 8 and 1 prepared using the usual ceramic technique as function of temperature t and composition x the dc electrical resistivity ϱ curie temperature t c.

Dc electrical properties of ferrites.

The micro structural and magnetic properties of ni 0 7 zn 0 3 fe 2 o 4 ferrite prepared by sol gel auto combustion method has been investigated 7 8 9 it was found that in the inverse spinel ni zn ferrite zn ions prefer to. The effect of al 3 ions on structural curie temperature dc electrical resistivity and dielecltric properties are presented in this paper. High permeability to magnetic fields is particularly desirable in devices such as antennas. Ferrite nanoparticles of the composition co 0 5 m 0 37 cu 0 13 fe 2 o 4 m ni zn and mg have been synthesized using sol gel auto combustion method.

The effect of ti al and mg ions on the electric and magnetic properties of ni zn ferrites was studied.

Dc electrical properties of mg substituted nicuzn ferrites read online aliuzzaman 1m. The dc electrical conductivity of ferrites is one of the important properties which gives the valuable information about the conduction mechanism.

Ferrites can have several different types of crystalline structures including spinel garnet perovskite and hexagonal. Nanosized cobalt ferrites having the general formula cofe 2 x al x o 4 for x 0 00 0 25 0 50 have been synthesized by the sol gel route. However this does not apply to automotive electronic devices particularly hev hybrid electric vehicle dc dc converters. From the analysis of powder x ray diffraction patterns the nanocrystallite size was calculated by the most.

Therefore in order to save energy dc dc converters for electronic devices use a power ferrite material that minimizes core loss in the operating temperature range generally about 60 to 100 c. Structural properties are investigated using powder x ray diffraction technique and the results showed a pure spinel crystal structures of the synthesized materials with lattice parameters in the range of 8 3331 8 4793 å. Discussion on electrical properties of ferrites is generally explained by carrier hopping model or band structure. Moreover electrical conductivity has a significant effect on the dielectric polarization in the spinel ferrites.
