What is Superconductivity in the new Nb5Si3−xBx phase about?

In the Nb-Si system the αNb 5 Si 3 phase is not a superconductor. Considering the high solubility of this phase for boron, in this work it has been evaluated the effect of boron doping in αNb 5 Si 3 on the electrical and magnetic properties of the produced materials. It has been shown that boron doping promoted superconductivity for all studied compositions. The Nb 5 Si 2.4 B 0.6 sample presented the maximum superconducting critical temperature (7.8 K) with upper critical magnetic field close to μ o H ∼ 4.2 T. Thus, this work shows for the first time superconductivity in a phase with Cr 5 B 3 -prototype structure.
