摘要：
In this study, a series of Ba0.8Ni0.2Fe(12-y--x)CexLayO19 (0( )<= x, y <= 0.3) hexaferrites was prepared by sol gel auto combustion method. The XRD was used for the structural analysis of prepared samples. The obtained XRD patterns confirmed the formation of M-type hexaferrites and the average crystallite size of the prepared samples was found in the range 19.51 to 32.58 nm. The electrical properties were investigated by two probe technique. It was revealed that the electrical resistivity of sample with La content is higher than that of the samples without La content. The maximum resistivity was found for the sample with x = 0.3, y = 0.3. The UV-vis results exhibit that the bandgap of the samples was increased with the inclusion of La and increases with the increase in La content.
