提出对高温超导及其相关材料进行系统深入的研究。基于他们在发现、合成和表征材料方面的专业知识,他们计划将研究重点放在三个高度相关的领域:(1)高压下的高温超导性,(2)超导态的磁性,(3)高温超导性的演变。通过对现有高温超导材料在高场压力下的电学、磁学、结构和光学性质的研究;通过超高压诱导非超导但相关的化合物的超导性;利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、磁通量动力学的物理和发现新的高温超导体的前景的宝贵信息。该研究最终将为科学研究提供更广泛的材料基础和更好的质量,并为实际应用提供更高的转变温度、更大的临界电流密度、更小的各向异性、更高的机械强度、更高的化学稳定性和更好的延展性。
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.
