压缩超导体的高转变温度超导性是当前材料科学研究的热点之一。然而，由于所需的氢气气氛和高压，合成和测量的超导性能是相当具有挑战性的。本研究利用气体加载系统和具有独特金刚石组件的金刚石对顶砧，开发了一个压缩超导磁体的合成和测量平台。未掺杂的金刚石绝缘层将氢气填充到样品室中，而硼掺杂的金刚石电极检测样品特性。利用该系统在PdHx上进行了超导电性的合成和观察。
High transition-temperature superconductivity in hydrides under compression is one of the hottest topics in materials science. However, the synthesis and measurement of the superconducting properties of hydrides are quite challenging because of the required hydrogen atmosphere and high pressure. This study developed a synthesis and measurement platform for superconducting hydrides under compression using a gas loading system and diamond anvil cell with unique diamond components. The undoped diamond insulation packs hydrogen into the sample chamber, and the boron-doped diamond electrodes detect the sample properties. The synthesis and observation of superconductivity were demonstrated on PdH x using the developed system.
