Study The Physical And Structural Properties Of A Commercial Ferrite And Its Applications

Samples of disk shaped from unknown commercial ferrite were produced. Structural investigations were performed to recognize the constituents, chemical formula, crystal structure, lattice constants and microstructure of the investigated ferrite . In additiOn the basis of magnetic transition such anomaly has been accounted for. According to the Seebeck coefficient measurements, the ferrite behaves as an n-type semiconductor. Moreover the density of charge carriers has been evaluated at different temperatureRegarding the Ac conductivity measurements, the Ac activation energy, frequency exponent factor and the relaxation time were revealed. On the other hand, the conduction mechanism in the ferrite was suggested to be small polaron quantum mechanical tunnelin
