Paper Title
Study of B-Site Dopants on Structure, Magnetic and Transport Properties of Some Perovskite Based Oxides

Abstract
The effects of Cu substitution at the B and B’ sites on the structure, magnetic and transport properties of LaSrCoRuO6 have been investigated. All the doped compositions crystallize in the monoclinic structure in the space group P21/n indicating a double perovskite structure. The Cu substitution strengthens the antiferromagnetic interactions since it does not favor formation of Ru-o-Ru or Co-O-Co networks. Keywords— Archtype Double Perovskite, antiferromagnetic interactions, monoclinic structure, magnetoresistance.
