Dc Electrical Properties Of Ferrites

High permeability to magnetic fields is particularly desirable in devices such as antennas.

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. Dc electrical properties of mg substituted nicuzn ferrites read online aliuzzaman 1m. Structural and electrical characterization of ni zn ferrites. And activation energies for electric conduction in ferrimagnetic e r and in paramagnetic f p region decrease as zinc ion substitution.

Moreover electrical conductivity has a significant effect on the dielectric polarization in the spinel ferrites. Although there are few reports on different properties of ni zn ferrite a systematic investigation about electrical properties is lacking so there is a need for investigation of electrical properties on ni zn ferrite to understand. Ferrites can have several different types of crystalline structures including spinel garnet perovskite and hexagonal. The dc electrical conductivity of ferrites is one of the important properties which gives the valuable information about the conduction mechanism.

Discussion on electrical properties of ferrites is generally explained by carrier hopping model or band structure. From the analysis of powder x ray diffraction patterns the nanocrystallite size was calculated by the most. 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. 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. 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. The effect of al 3 ions on structural curie temperature dc electrical resistivity and dielecltric properties are presented in this paper. The most important properties of ferrites include high magnetic permeability and high electrical resistance.
