Rietveld refinement of the X-ray diffraction pattern showed that GCCO is crystallized in a monoclinic structure with space group <i>P2</i>_<i>1</i>/<i>n</i>, which is further confirmed by Raman spectroscopic analysis. The absence of perfect long-range ordering between Co and Cr ions is confirmed by the mixed valence states of Co and Cr. A Néel transition was observed at a higher temperature of <i>T</i>_N = 105 K compared to that of an analogous double perovskite Gd₂FeCrO₆ due to a greater degree of magneRSC advances17545-17555https://www.ebi.ac.uk/biostudies/studies/S-EPMC10258676biostudies-literatureStructural, magnetic and optical properties of disordered double perovskite Gd₂CoCrO₆ nanoparticles.PMC10258676Syed IMBasith MAHosen MJfalseStructural, magnetic and optical properties of disordered double perovskite Gd₂CoCrO₆ nanoparticles.We have synthesized disordered double perovskite Gd₂CoCrO₆ (GCCO) nanoparticles with an average particle size of 71 ± 3 nm by adopting a citrate sol-gel method to investigate their structural, magnetic, and optical properties.
