Abstract
We argue that the recent Raman spectroscopy observation of a sharp mode in s-wave superconducting VSi is due to a competing d-wave pairing state. We present microscopic arguments for the origin of this d-wave order. We further argue that the d-wave order explains the observed shrinking of the vortex core structure at anomalously low magnetic fields and the large anisotropy observed in the upper critical field.
