Dc Electrical Properties Of Ferrites

Ferrites can have several different types of crystalline structures including spinel garnet perovskite and hexagonal.

Dc electrical properties of ferrites.

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

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 most important properties of ferrites include high magnetic permeability and high electrical resistance. 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. 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 al 3 ions on structural curie temperature dc electrical resistivity and dielecltric properties are presented in this paper. This is an open access article distributed under the creative commons attribution license which permits unrestricted use distribution and reproduction in any medium provided the. The effect of ti al and mg ions on the electric and magnetic properties of ni zn ferrites was studied. Moreover electrical conductivity has a significant effect on the dielectric polarization in the spinel ferrites.

Discussion on electrical properties of ferrites is generally explained by carrier hopping model or band structure. 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. And activation energies for electric conduction in ferrimagnetic e r and in paramagnetic f p region decrease as zinc ion substitution. However this does not apply to automotive electronic devices particularly hev hybrid electric vehicle dc dc converters.
