synthesis,optimization and characterization of the physical properties of nanocrystal material

For its importance and technical application aspects, ferrites are the subject of many articles and reports. Recently ferrites have been involved in the new branch of the so-called nanotechnology. Besides, nanoferrites have potential application in many fNanoferrites system of Mn1-x Znx Fe2O4 with 0 X 1.were synthesized through a coprecipitation technique. The optimum conditions for an exchange reaction between solutions of chlorides were achieved. Stoichiometric single phase spinel of Mn1-x Znx Fe2O4 witTo characterize the ferrite, the electrical conductivity AC and DC, dielectric constants and initial permeability were measured against temperature over a wide range of frequency from 0 up to 5 MHz.According to the electrical conductivity, the CNCP samples of Mn1-x Znx Fe2O Ferrite behave as a semiconductor over the whole range of temperature (from 300 K up to 1273K) and applied field with frequency up to 5 MHz.
