Preparation, characterization and magnetic properties for the sample obtained from the polymeric precursor technique
Author(s): Aloke Chattopadhyay
Abstract: Preparation of ceramic oxide by polymeric precursor technique is a new advancement in Materials Science. Preparation of Y1Ba2Cu4O8 by polymeric precursor technique has been already reported in the Journal of the Indian Chemical Society. But the sample contains sodium oxide impurity. To control formation of sodium oxide by product, it has been already found that filtration of the precipitate containing mass, obtained during preparation of polyvalent metal ion bound polyacrylate before drying, is necessary. By adopting this modification, an oxide sample has been prepared, in present investigation, which is expected to be antiferromagnetic as is evidenced by ZFC curve. To characterize the sample, XRD, SEM and EDS are done and reported in this present investigation. Magnetic measurements are done to understand antiferromagnetic nature.
