Abstract
•It is shown demonstrated that B can substitute Ge atoms in the Ta5GeB2phase.•It is shown demonstrated that Ta5GeB2has a Cr5B3 prototype structure.•Ta5GeB2 is a new example of stoichiometric Cr5B3phase.•Ta5GeB2 is found to be a new superconductor at 3.8 K.•Ta5GeB2 is a BCS superconductor.
We report superconductivity at TC ∼3.8 K in the new ternary phase Ta5GeB2. Bulk superconductivity is confirmed by magnetization, electrical resistivity and heat capacity measurements, the results showing conventional bulk superconductivity. Ta5GeB2 is a further example of a stoichiometric T2 phase with Cr5B3 prototype structure.
