论文摘要
We have synthesized high-entropy-alloy-type (HEA-type) RE123 superconductors Y0.28Nd0.16Sm0.18Eu0.18Gd0.20Ba2Cu3O7-d and Y0.18La0.24Nd0.14Sm0.14Eu0.15Gd0.15Ba2Cu3O7-d with a超导过渡温度（TC）超过90K。从heater型和常规RE123样品之间的比较中，我们发现稀土位点的混合熵不会影响RE123样品的TC和临界电流密度（JC）。对于所有检查的样品，发现正栓性是TC和JC的重要参数。在近骨四方边界附近的政权中，Hee型样品的JC大于常规型样品的JC，这表明Hee-Type RE123可能对改善低正晶性的结构中的JC可能很有用。
We have synthesized high-entropy-alloy-type (HEA-type) RE123 superconductors Y0.28Nd0.16Sm0.18Eu0.18Gd0.20Ba2Cu3O7-d and Y0.18La0.24Nd0.14Sm0.14Eu0.15Gd0.15Ba2Cu3O7-d with a superconducting transition temperature (Tc) exceeding 90 K. From comparison between HEA-type and conventional RE123 samples, we found that the mixing entropy at the rare earth site does not affect Tc and critical current density (Jc) of the RE123 samples. For all the examined samples, orthorhombicity was found to be an essential parameter for Tc and Jc. In the regime near orthorhombic-tetragonal boundary, Jc for the HEA-type sample was larger than that of conventional-type samples, which suggests that HEA-type RE123 may be useful to improve Jc in the structure with low orthorhombicity.
