»ã±¨±êÌâ(Ó¢ÎÄ)£ºInterplay between structural anomaly, magnetism, and superconductivity in Mo3Sb7

»ã±¨ÄÚÈݼò½é£ºDespite a relatively low superconducting transition temperature Tc = 2.08 K, the Zintl compound Mo3Sb7 has attracted considerable interest due to the possible involvement of magnetism in superconducting pairing, and promising thermoelectric performance with proper doping. Mo3Sb7 crystallizes in Ir3Ge7-type cubic structure with space group Im3m at room temperature. A structure transition from cubic to tetragonal (I4/mmm) was observed at 53 K and this symmetry lowering is accompanied by the opening of a 120 K spin gap. So Mo3Sb7 provides an interesting platform to study the interplay between structural anomaly, magnetism, and superconductivity. In this talk, I will present the crystal growth, intrinsic physical properties of Mo3Sb7, and how chemical and hydrostatic pressures disturb the complex interplay between structural anomaly, magnetism, and superconductivity.
