Abstract:
Superconductivity was observed in a majority of 3d transition metal compounds except for the Cr- or Mn-based compounds. It is thus of high interest in exploring possible superconductivity in those systems. In this talk, I will present the discovery of superconductivity on the verge of antiferromagnetic order in CrAs and MnP via the application of external high pressure. The close proximity of superconductivity to an antiferromagnetic order highly suggests an unconventional pairing mechanism for both CrAs and MnP. The present finding opens a new avenue for searching novel superconductors in the Cr and Mn based systems.
