About this document
Two-Gap Superconductivity in V3Si Crystals by Asegdew Fitawok is a document available to read on EtoBox.
The document discusses evidence from microwave response measurements of V3Si single crystals that provides support for two-gap superconductivity in the material. Key findings include: 1) The temperature dependence of the surface reactance X(T) can be described by an activation energy Δ2 ≈ 0.95Tc, much smaller than the BCS value, suggesting two distinct energy gaps. 2) The "coherent peak" in the real part of conductivity σ
