Effect of Molar Ratio on Crystal Structure and Surface Morphology of Nd1(Fe)xBa2-xCu3O7 Oxide Alloy by Solid-State Reaction Method

Abstract

Processing of materials Nd1(Fe)xBa2-xCu3O7 oxide alloy by varying the molar ratio of Fe doping, which x varied from +0.1 to +0.3 has been developed by solid-state reaction method. This research has shown that the hkl plane of the sample has c-axis oriented, i.e., (005), (006), (007), (008) and (009), respectively. All of the samples have the most dominant peak of (006) with the crystal structure is tetragonal. The molar ratio of the samples having a composition of Nd:Ba:Fe:Cu = 1:(2 - x):x:3.1. Other results, by SEM characterization, indicate that variation of Fe doping influence of the grain size and grain orientation of the various samples. The result of XRD and SEM characterization analysis indicates that Fe doping has an effect on the crystal structure, composition, and surface morphology of Nd(Fe)BCO oxide alloy.
