Synthesis and Characterization of Intergrowth Type Perovskite Oxide NdSr₂MnCrO₇

Abstract

A new Ruddlesden-Popper phase NdSr2MnCrO7 has been prepared by the standard ceramic method. The powder X-ray diffraction studies suggest that the phase crystallizes with tetragonal unit cell in the space group I4/mmm. The electrical transport properties show that the phase is an electrical insulator and the electrical conduction in the phase occurs by a 3D variable range hopping mechanism. The magnetic studies suggest that the ferromagnetic interactions are dominant.

“…However, very few reports have appeared on the effect of Cr-doping at Mn site for bilayered perovskite manganites [17][18][19]. We have already reported Nd-based Cr doped bilayer manganite NdSr 2 MnCrO 7 synthesized by ceramic method [20] but in this paper much has been left about the details of its crystal structure refinements. In the present work, we have synthesized NdSr 2 MnCrO 7 compound by citrate-gel method and the effect of increasing Nd content on the crystal structure, magnetic and electric transport properties has been investigated.…”

“…Further, it is known that nano-crystalline rare-earth (A) transition-metal (B) oxides belong to ABO3 perovskite structure, B is usually a 3d or 4d transition metal surrounded by six oxygen atoms in octahedral coordination and A is normally a rare earth cation, 12coordinate by oxygen atoms, have been extensively studied for many applications [2][3][4][5].…”
