X-ray and magnetic studies of Zn2+ substituted Ni-Pb ferrites

Seven samples of the polycrystalline, Ni1.25-xZnxPb0.25Fe1.5O4 (x = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6) ferrites, were prepared by usual double sintering ceramic method. X-ray diffraction patterns of the samples revealed single-phase cubic spinel structure. The magnetic properties were investigate...

Description
Summary:Seven samples of the polycrystalline, Ni1.25-xZnxPb0.25Fe1.5O4 (x = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6) ferrites, were prepared by usual double sintering ceramic method. X-ray diffraction patterns of the samples revealed single-phase cubic spinel structure. The magnetic properties were investigated by means of magnetization and a.c. susceptibility (χ) measurements. A.C. susceptibility was measured from room temperature to the Curie temperatureTC) of the samples. Variation of a.c. susceptibility (χ) with temperature showed that the samples withx= 0.3 and 0.5 contain single-domain (SD) particles whereas the samples withx= 0.4 and 0.6 showed multi-domain (MD) nature. Values of Curie temperature (TC)as obtained from the study of variation of a.c. susceptibility with temperature were found to decrease with increase in the Zn2+ concentration (x bd. Magnetic measurements showed increase in magnetization as Zn2+ content was increased from 00 to 0.5. Further increase in Zn2+ contentx bd reduces the magnetization.
