چکیده انگلیسی
Samples of Ni1âyZnyCu0.3Fe1.7O4; 0.0⩽y⩽0.6 were prepared by the solid state reaction method. X-ray investigations were carried out in order to assure the formation of the samples in single spinel phase. The analysis of X-ray data shows that the unit cell parameter increases with increasing Zn concentration and ascribed to the variation of the predicted cation distribution. Seebeck coefficient measurements were performed to know the type of charge carriers participating in the conduction mechanism. The magnetic susceptibility for the prepared samples was measured using Faraday's method at different temperatures as a function of the magnetic field intensity. The magnetic parameters were calculated from the magnetic susceptibility data, in the temperature range (300-800 K) at three different magnetic field intensities of (1280, 1733 and 2160 Oe). The effective magnetic moment (μeff) showed that, the critical Zn content was y=0.2.
