Effect of pH on magnetic, thermal and dielectric properties of SnO2 nanomaterials

The SnO2 nano materials were synthesized by chemical precipitate technique. The pH of the reaction solution was varied from 7 to 9 insteps of 1. From the powder XRD the particle size was calculated using Scherrer formula, it varied from 57 to 66 nm for different pH values. The FE-SEM analysis reveals the morphology of SnO2 nanomaterials. Vibrating sample magnetometer (VSM) results demonstrates that the SnO2 samples exhibit perfect room temperature ferromagnetism (RTFM). The sample was characterized by TGA/DTA. Measurement of different electrical parameters with frequency (50 Hz-5 MHz) has been carried out different temperature. (C) 2016 Elsevier B. V. All rights reserved.
