Abstract
Tungsten films were found to be superconducting at 3.2°K. Upon investigation by x‐ray and electron diffraction, a β‐W (A15) structure was evident. Superconducting tunneling studies revealed that the ratio 2Δ(0)/kTc varied from 2.32 and 3.64 and Δ(T)/Δ(0) vs T/Tc followed the BCS theory.Keywords
