Abstract: We report superconductivity at T C ∼3.8 K in the new ternary phase Ta 5 GeB 2 . Bulk superconductivity is confirmed by magnetization, electrical resistivity and heat capacity measurements, the results showing conventional bulk superconductivity. Ta 5 GeB 2 is a further example of a stoichiometric T 2 phase with Cr 5 B 3 prototype structure. [ABSTRACT FROM AUTHOR]
