Abstract
In this research paper it was studied the electric behaviour of ferrite zinc material[1][3][5] [9][12][16][19][24] added to it manganese iron (Mn+2) [2][4][11][13][19][20][25] according to the chemical formula: Mnx, Zn1-x, Fe2O4; X= 0.0, 0.2, 0.4 and 0.6, which was prepared by the traditional ceramic method. This matter is classified as one of the ferromagnetic [9][14][16][17] materials of multi-crystalline structure. X-ray diffraction technology was used for all samples and the electric conductivity [1][3][5][6][7] was measured at a certain range of temperatures and frequencies.
