Two new high-pressure nickel-based superconducting materials have emerged, a significant breakthrough by Chinese scientists.

Chinese scientists have made another important breakthrough in the field of nickel-based high-temperature superconductors. The team of Xue Qikun and Chen Zhuoyu from the National Key Laboratory of Quantum Functional Materials at Southern University of Science and Technology and the Physics Department, as well as the Quantum Science Center of Guangdong-Hong Kong-Macao Greater Bay Area, collaborated with the team of Shen Dawei from the University of Science and Technology of China. The team recently published their latest research results in the international academic journal "Nature": Under extreme oxidizing conditions, the team successfully created two new nickel-based high-temperature superconductor materials by artificially designing atomic stacking sequences. At the same time, with the help of angle-resolved photoemission spectroscopy technology, researchers identified the key electronic band structure closely related to the superconducting state, providing important experimental evidence for revealing the mechanism of nickel-based high-temperature superconductivity.
