The application of superconducting materials to power transmission systems has always been a scientist's dream. The reporter learned from the Chinese Academy of Sciences Hefei Institute of Materials Science and Technology on the 10th that the researcher of the strong magnetic field science center of the institute found in experiments that a kind of superconducting material has a high current carrying capacity, making the human distance from the dream of the superconducting power transmission system a step further.
The application of superconducting materials to power transmission systems has always been a scientist's dream. However, great challenges have been encountered in practical practice. One of them is to find suitable superconducting materials with excellent flexibility. In light of this, exploring superconducting materials with practical application value has been a hot research topic in condensed matter physics, materials physics, and industrial fields for the past several decades.
Recently, under the leadership of Academician Zhang Yuheng, the chief scientist of the Strong Magnetic Field Science Center of the Chinese Academy of Sciences, the Zhang Changjin research team of his team has made important progress in the application of new superconducting materials. The researchers successfully obtained Nb2PdxS5-y (0.6) with excellent superconducting transitions using a high-temperature solid-state reaction method. In addition, the research team also used the 16 Tesla physical property testing system of the Strong Magnetic Field Science Center of the Chinese Academy of Sciences to measure the superconducting properties of the sample under a strong magnetic field, and found that the upper critical magnetic field and the critical current density change with the diameter of the sample. . The upper critical magnetic field and critical current density of the system rapidly increase with decreasing sample diameter. For example, the upper critical magnetic field of a sample with a diameter of 1.5 μm is about 34 Tesla, and the upper critical magnetic field of a sample with a diameter of 0.5 μm is Above 40 Tesla, this extremely high upper critical magnetic field and critical current density indicate that the material has a high current carrying capacity in a strong magnetic field. It is reported that this research work has been funded by the Chinese Ministry of Science and Technology, the National Natural Science Foundation of China and the Chinese Academy of Sciences. The research results were published in the newly published "American Chemical Society".
