Beijing - A team of Chinese scientists has developed a high-temperature nickelate superconductor at room pressure.
According to a research paper published Tuesday (February 18) in the journal Nature, a team of researchers from SUSTech, the Guangdong-Hong Kong-Macao Greater Bay Area Quantum Science Center, and Tsinghua University reported nickelate superconductivity at room pressure. The initial transition temperature was reported to exceed 40 K, or about minus 233 degrees Celsius, and there was definite evidence of zero electrical resistance and magnetic field expulsion.
The findings establish nickelate as the third class of high-temperature superconductors, following cuprate- and iron-based systems, capable of operating at ambient conditions. The research also sheds light on the mechanism of high-temperature superconductivity.
