To Study the Effect of Calcinations Temperature on the Structural and Magnetic Properties of ZnMnO3±δ Nanocrystallines

Abstract

In present scenario, the technological applications of nanomaterials are at key position because of unique in Physico-chemical property at this scale. The present research work explored the effect of concentration of Zn element on structural and morphological modifications in Zinc Oxide Manganese Oxide nano-crystalline. In this research work, nano-sized Zinc Oxide Manganese Oxide sample was synthesized via advanced co-precipitation chemical protocol. The specimens have been calcined at 200⁰C, 400⁰C, 600⁰C for a time span of 2hours. The XRD results reflects that The crystalline size of newer nano-crystallines were increase in particle size with increase in calcinations temperature Zinc Oxide  Manganese Oxide hexagonal structure .The FTIR tools was used to examine the purity of samples and entities  of Zinc Oxide  Manganese Oxide structural material. The magnified images of samples were seen through FESEM and HRTEM tools and exhibited structure were 2-D nano-sheets were in formation. The M-H curve of calcined samples concluded that nature of all calcined samples were paramagnetic in nature and magnetic susceptibility shows inverse behaviour with rise of temperature and follow Curie-Weiss Law of magnetism.
