摘要

合成了高熵单相超导氧化物Y0.2Nd0.2Eu0.2Sm0.2Ho0.2Ba2Cu3Oy。对含氧量不同的样品进行热重、x射线衍射和磁性能测定。正交性、临界温度和临界电流随氧非化学计量值y的增长而增长，对应于“低熵”yba2cu3oy型超导体。氧含量的增加导致CuO2“屈曲”层的减少，而不导致Ba-O距离的减小。

High-Entropy Superconducting Oxides (Y,Nd,Eu,Sm,Ho)Ba2Cu3Oy with Different Oxygen Contents

High-entropy single-phase superconducting oxide Y_0.2Nd_0.2Eu_0.2Sm_0.2Ho_0.2Ba₂Cu₃O_y 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” YBa₂Cu₃O_y-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.
