Investigation of Superconducting Gap Structure in TbFeAsOF using Point Contact Andreev Reflection
K. A. Yates, K. Morrison, Jennifer A Rodgers +4
Bulk samples of TbFeAsOF (T(on) = 50K) were measured by point contact Andreev reflection spectroscopy. The spectra show unambiguous evidence for multiple gap-…
Point contact Andreev reflection spectroscopy of NdFeAsO_0.85
K A Yates, L F Cohen, Zhi-An Ren +4
The newly discovered oxypnictide family of superconductors show very high critical temperatures of up to 55K. Whilst there is growing evidence that suggests a nodal order parameter…
Evidence for Supercurrent Connectivity in Conglomerate Particles in NdFeAsO1-d
J D Moore, K Morrison, K A Yates +11
Here we use global and local magnetometry and Hall probe imaging to investigate the electromagnetic connectivity of the superconducting current path in the oxygen-deficient fluorin…
Strong influence of boron precursor powder on the critical current density of MgB2
S. K. Chen, K. A. Yates, M. G. Blamire +1
The influence of the nature of the boron precursor on the superconducting properties of polycrystalline MgB2 was studied. Critical current densities for the MgB2 made from high pur…
Disorder induced collapse of the electron phonon coupling in MgB observed by Raman Spectroscopy
K. A. Yates, G. Burnell, N. A. Stelmashenko +4
The Raman spectrum of the superconductor MgB has been measured as a function of the Tc of the film. A striking correlation is observed between the onset and the frequ…
