Superconductivity above 10 K in a novel quasi-one-dimensional compound

Phys.org  August 13, 2018
Researchers in China succeeded in synthesizing the new Q1D K2Mo3As3 compound whose Tc value exceeded 10 K. Bulk superconductivity below 10.4 K was confirmed by electrical resistivity, magnetic susceptibility, and heat capacity measurements. The K2Mo3As3 is the first MoAs-based superconductor and possesses the record Tc in all Q1D superconductors. This discovery indicates that Cr and Mo based Q1D superconductors may share some common underlying origins within the similar structural motifs and will help to uncover the exotic superconducting mechanism in low dimensional materials… read more.
