The First Cr-based Nitrides Superconductor Pr3Cr10-xN11

Caption

(a) The face-centered cubic cell of Pr3Cr10-xN11 with three kinds of building blocks: Pr6N9, Cr8N13 and Cr6, respectively. (b) Temperature dependence of the resistivity for Pr3Cr10-xN11 from 1.8 to 300 K at the zero field. (c) The temperature dependence of the upper critical magnetic field. The inset shows the temperature dependence of the resistivity at different fields.
