Investigation of Superconducting Gap Structure in TbFeAsO${}_{0.9}$F${}_{0.1}$ using Point Contact Andreev Reflection

K. A. Yates, K. Morrison, Jennifer A Rodgers +4

Bulk samples of TbFeAsO${}_{0.9}$F${}_{0.1}$ (T${}_c$(on) = 50K) were measured by point contact Andreev reflection spectroscopy. The spectra show unambiguous evidence for multiple gap-…
