Abstract
This paper explores a newly created double perovskite substance named Sr2CrMnO6 (SCMO), produced using a gel combustion method. The research delves into the material’s structural, optical, and magnetic characteristics. The material’s purity and the development of a monoclinic structure with space group P21/n1 (#14) were verified using Rietveld refinement of the X-ray diffraction pattern. The material’s band gap, determined to be 2.5 eV through UV-Vis spectroscopy and Tauc plot analysis, indicates its potential for optoelectronic applications. At room temperature, SCMO displays paramagnetic behavior and a ferromagnetic Curie temperature of approximately 250 K, suggesting its suitability for applications in low-temperature spintronics.
期刊介绍：
The Journal of Superconductivity and Novel Magnetism serves as the international forum for the most current research and ideas in these fields. This highly acclaimed journal publishes peer-reviewed original papers, conference proceedings and invited review articles that examine all aspects of the science and technology of superconductivity, including new materials, new mechanisms, basic and technological properties, new phenomena, and small- and large-scale applications. Novel magnetism, which is expanding rapidly, is also featured in the journal. The journal focuses on such areas as spintronics, magnetic semiconductors, properties of magnetic multilayers, magnetoresistive materials and structures, magnetic oxides, etc. Novel superconducting and magnetic materials are complex compounds, and the journal publishes articles related to all aspects their study, such as sample preparation, spectroscopy and transport properties as well as various applications.
