Abstract
High-entropy single-phase superconducting oxide Y0.2Nd0.2Eu0.2Sm0.2Ho0.2Ba2Cu3Oy was synthesized. For samples with different values of oxygen content thermogravimetry, x-ray diffraction and magnetic properties were measured. Orthorombitity, critical temperature, and critical current grow with oxygen nonstoichiometry value y and corresponds to those for “low-entropy” YBa2Cu3Oy-type superconductors. The increase of the oxygen content leads to a decrease of “buckling” CuO2 layers and does not lead to a decrease in the Ba–O distance.
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.
