Our country's scientists have created a new record for the transition temperature of nickel-based superconductors.

The discovery of high-temperature superconducting materials has always been a goal pursued by scientists around the world. Recently, Chinese scientists have developed a new nickel-based superconductor, setting a new record for the superconducting transition temperature of this type of material. The achievement was published online in the international journal Nature on December 3. Superconductivity refers to the phenomenon in which certain materials suddenly lose resistance and can repel magnetic fields below a specific temperature, allowing for lossless transmission of electric current. The newly developed superconducting material belongs to the nickel salt system and is the third type of unconventional high-temperature superconductor after copper-based and iron-based superconductors. However, the synthesis and performance measurement of such materials are very difficult. The research was conducted by a team led by researcher Zeng Qiaoshi of the Beijing High Pressure Science Research Center and Professor Zhang Junjie of Shandong University. "This is the first time that nickel-based superconducting materials have approached the '100K superconductivity,' laying an important foundation for exploring higher-temperature superconducting materials," said Zeng Qiaoshi. With scientists continuously breaking through in the field of high-temperature superconductivity, the possibility of achieving superconductivity at room temperature is moving from science fiction into reality.
