Superconductivity in SrTa sub(2)S sub(5)

A strontium tantalum sulfide, SrTa sub(2)S sub(5), has a hexagonal structure with lattice constants of a identical with 3.32 and c identical with 24.1 angstroms. With decreasing temperature the electrical resistivity decreases monotonically and exhibits an abrupt superconducting transition at 3.16 K...

Description
Summary:A strontium tantalum sulfide, SrTa sub(2)S sub(5), has a hexagonal structure with lattice constants of a identical with 3.32 and c identical with 24.1 angstroms. With decreasing temperature the electrical resistivity decreases monotonically and exhibits an abrupt superconducting transition at 3.16 K (midpoint). The diamagnetic susceptibility is observed below T sub(c). The magnetic susceptibility is nearly independent of temperature above T sub(c) and shows Pauli paramagnetism.
