With the support of electrical transport and magnetic measurement systems of Steady High Magnetic Field Facility (SHMFF)‚ a research team from Hefei Institutes of Physical Science (HFIPS)‚ Chinese Academy of Sciences (CAS)‚ discovered a new superconducting material called (InSe2)xNbSe2‚ which possesses a unique lattice structure. The superconducting transition temperature of this material reaches 11.6 K‚ making it the transition metal sulfide superconductor with the highest transition temperature under ambient pressure.
