通过最近两个高温超导体的研究，讨论了多探针在材料科学中的协同应用，并对协同应用的未来进行了前景展望。对于氢掺杂的铁基超导体，其显示出作为氢浓度的函数的双峰超导圆顶，中子、μ子和同步加速器X射线探针的交响乐使用发现了第二反铁磁（AF）相及其与第一AF相相比的对比特征。用中子和同步辐射X射线探针研究了微量空穴掺杂的Mott绝缘体La2CuO4中Ni杂质引起的AF有序的剧烈变化。交响乐使用这些探针澄清了微观双电子态的Cu和Ni在这个系统中。
Symphonic use of multiple probes for materials science is discussed through two recent studies on high-T c superconductors, and a future prospect of the symphonic use is given. For a hydrogen-doped iron-based superconductor, which shows a double-peaked superconducting dome as a function of hydrogen concentration, symphonic use of neutron, muon and synchrotron x-ray probes discovered a second antiferromagnetic (AF) phase and its contrasting feature compared to the first AF phase. A drastic change of the AF order by Ni impurities in slightly hole-doped La 2 CuO 4, a Mott insulator, has been studied by using neutron and synchrotron x-ray probes. The symphonic use of these probes clarified the microscopic dual electronic states for both Cu and Ni in this system.
