对高温超导及相关材料进行了系统深入的研究。基于他们在材料发现、合成和表征方面的成熟专业知识,他们计划将他们的研究重点放在三个高度相关的领域:(1)高压下的高温超导;(2)超导状态的磁性;(3)高温超导的演化。通过研究现有高温超导材料在高场压力下的电、磁、结构和光学性质;通过在超高压下诱导非超导但相关化合物的超导电性;通过使用我们开发的特殊技术合成化合物,将获得关于高温超导的发生、磁通动力学的物理以及发现新的高温超导体的前景的宝贵信息。这项研究将最终导致高温超导的发展,其材料基础更广,科学研究质量更好,实际应用中的转变温度更高,临界电流密度更大,各向异性更小,机械强度更大,化学稳定性更高,延展性更好。
英文摘要
A Systematic in-depth investigation of high temperature superconducting and related materials is proposed. Based on their established expertise in the discovery, synthesis, and characterization of materials, they plan to focus their research efforts on three highly related areas: (1) high temperature superconductivity under high pressures, (2) the magnetic properties of the superconducting state, and (3) the evolution of high temperature superconductivity. By examining the electrical, magnetic, structural and optical properties of existing high temperature superconducting materials under pressures in high fields; by inducing superconductivity in non-superconducting but related compounds under ultra-high pressures; and by synthesizing compounds using special techniques developed by us, invaluable information will be obtained about the occurrence of high temperature superconductivity, the physics of magnetic flux dynamics and the prospect of discovering new high temperature superconductors. The study will eventually lead to the development of high temperature superconductivity with a broadened material base and better quality for scientific study and with higher transition temperatures, greater critical current density, smaller anisotropy, greater mechanical strength, higher chemical stability, and improved ductility for practical applications.
