Dimensionality of superconductivity in the transition metal pnictide WP


الملخص بالإنكليزية

We report theoretical and experimental results on transition metal pnictide WP. The theoretical outcomes based on tight-binding calculations and density functional theory indicate that WP exhibits the nonsymmorphic symmetries and is an anisotropic three-dimensional superconductor. This conclusion is supported by magnetoresistance experimental data as well as by the investigation of the superconducting fluctuations of the conductivity in the presence of a magnetic external field, both underlining a three dimensional behavior.
