Preparation and characterization of R2CoMnO6 (R=La, Nd) via PVA sol-gel route

La2CoMnO6 and Nd2CoMnO6 powders were successfully synthesized by applying the polyvinyl alcohol (PVA) sol-gel method. The synthesized nanoparticles were characterized by DSC, TG, FT-IR, XRD, Raman spectroscopy, and SEM. XRD analysis revealed that single phase La2CoMnO6 powders was directly synthesized through the charring procedure and no intermediate phase appeared. However, the well-crystallized monophasic Nd2CoMnO6 was synthesized at a calcination temperature of 600 degrees C for 2 h. La2CoMnO6 and Nd2CoMnO6 powders showed paramagnetic behaviors at room temperature.

Automated summary

La2CoMnO6 and Nd2CoMnO6 powders were successfully synthesized using the PVA sol-gel method and characterized via various techniques. Different synthesis conditions were found to produce either single phase or well-crystallized monophasic nanoparticles with paramagnetic behaviors at room temperature.
