我科学家创造镍基超导体转变温度新纪录

Core Insights - The research team led by Professors Zhang Junjie and Tao Xutang from Shandong University has achieved a significant breakthrough in nickel-based superconductors, developing a new material that sets a record for the highest superconducting transition temperature (Tc) in this category at 96K (-177.15℃) [1][2] Group 1: Research Breakthroughs - The newly developed nickel-based superconductor surpasses previous records, with the highest Tc now at 96K, compared to the previous maximum of 83K (-190.15℃) [1] - The research was published in the international journal "Nature," highlighting its importance in the field of high-temperature superconductors [1] Group 2: Methodology and Innovations - The team introduced a novel method called "atmospheric pressure flux method," utilizing potassium carbonate as a flux to grow single crystals at atmospheric pressure, which reduces costs and enhances the feasibility of crystal preparation [2] - A key finding of the research is the correlation between lattice distortion and superconducting temperature, indicating that greater lattice distortion leads to higher Tc [1][2]
