A µSR stoichiometry study of TixV1-x alloys – superconductivity in the presence of itinerant spin fluctuations

Abstract: This is a continuation proposal, for work carried out previously on the EMU and MuSR spectrometers. We have determined that spin fluctuations are present in this system, by directly measuring their fluctuation rate, and have also fully characterized the vortex lattice state for one particular stoichiometry. We now need to determine how the spin fluctuation behaviour changes with the Vanadium content, as this will allow us to see the importance of the spin fluctuations in the superconductivity - are the phenomena intrinsically linked, or coincidentally present in the superconducting state? The former exciting possibility sees this seemingly conventional system exhibiting an unconventional pairing mechanism, with Cooper pairs that are bound not via the electron-phonon interaction, but by fluctuating spins. This would provide a link to the physics of the high-Tc cuprate superconductors.
