Synthesis and Characterization of Nanostructured LaNiO3

Tanya Jamwal

Abstract


In this world synthesis of LaNiO3 have been carried out by co-precipitation method respectively. Powder x-ray diffraction studies confirmed the formation of rhombohedral LaNiO3. LaNiO3 is known to have rhombohedrally distorted perovskite structure, and the lattice parameters of the rhombohedral unit cell and the pseudocubic unit cell are a = 5.46¡ and ¢ = 60.8o and a = 3.84Å respectively. The superconductivity in these oxides is a novel phenomenon, even the non-conducting perovskite oxides are interesting in their own oxides.


Keywords
