Superconductivity in epitaxial PtSb(0001) thin films

Building on earlier reports of superconductivity in bulk PtSb, we present a systematic study of superconductivity in epitaxial PtSb(0001) thin films grown on SrF 2 ( 111 ) . Electrical transport measurements reveal a superconducting transition at T c = 1.72 K . The field-induced...

Distinct lattice and charge excitations in AV3Sb5 kagome superconductors

The kagome superconductor family A V 3 Sb 5 ( A = Cs, Rb, K) provides a rich platform for exploring diverse electronic symmetry breaking phenomena, including superconductivity and various forms of density wave orders. Although these compounds share the identical lattice structure...

Bi[IrBi 6 I 12 ], Ag 3 [IrBi 6 I 12 ], and Bi x Cu 3–3 x [IrBi 6 I 12 ]: Rock‐Salt Superstructures Based on Heavy‐Atom Clusters

The bismuth‐rich subiodides Bi[IrBi 6 I 12 ], Ag 3 [IrBi 6 I 12 ], and Bi x Cu 3–3 x [IrBi 6 I 12 ] were synthesized by high‐temperature reactions in sealed silica ampules and characterized by powder and single‐crystal X‐ray diffraction, differential scanning calorimetry, energy‐...
