Transition metal oxide (TMO) materials contain transition elements and oxygen. Both insulation and poor-quality metal belong to this group. It may happen that the same material can impart both types of transport properties. When the temperature or pressure changes, metal-insulator transition is possible. There are few superconductors that are transition metal oxides. Valence electrons are present in more than one shell in this type of compound. But most transition metals have an oxidation state. Transition metal oxides are not associated with activation energy; therefore it is better than non-transition metal oxides. Transition metals have free d orbitals, so they are basically called catalysts. The metal surface has adsorbed the reagent and the substrate and reagent are bonded together by a clamp called d orbitals. Vacant d orbitals behave similarly to the energy gap, so transition metals have different colors. 1.2 Transition Metal Oxide Properties There are many types of distortions that occur in the ideal perovskite structure due to the inherent flexibility within the perovskite structure. Resulting in the inclination of the octahedron. Then the displacement of the cations from the centers of their respective coordination in the polyhedron occurs. The distortion of the octahedron is accelerated by electronic factors. Most of the physical properties of the perovskite structure depend on these distortions. In particular the electronic, magnetic and dielectric properties that are so important for many applications of perovskite materials. These materials have several useful magnetic and electronic properties. Most of the properties depend on some defects such as vacancies, dislocations, stacking defects, grain boundaries and... paper center... gnetic. This new magnetic state arises from the fact that the spins interact via the double exchange interaction. Subsequently the insulating state changes to semiconductor. Furthermore, the general concept is that ferromagnetic materials favor metallicity. Materials with perovskite structure have numerous studies in the last decade. Their structure and electrical and magnetic properties have been well established. However, a detailed study related to the type of double perovskite materials is still lacking in the literature. In this report an effort is made to study the behavior of some double perovskite materials in detail and then compare them with their perovskite counterpart, especially their structure, morphology and electrical behavior. These short studies will provide a baseline for selecting these materials for technological applications.
