Effect of Na Substitution on Rare-Earth Manganites

Abstract

An effort is made to study the effect of alkali metal substitution in particular Na, on the rare earth side of manganites of La, Nd and Pr. The samples are prepared by wet-chemical route known as Pyrophoric method. The structural characterization of the samples is carried out through detail Reitveld analysis of the XRD data which shows all the samples are single phase and stoichiometric. The granular information and sizes is probed through the SEM analysis. The star like structures of the material is the unique features of samples in the vicinity of the nano order. However the transport properties are unique among the separate constituents of the Na and rare earth combinations starting from pure insulator to metal-insulator transition.
