Abstract

rradiated single crystals, with columnar defect density corresponding to a matching field B-phi = 25 T. The H-c2,(c) (T) is close to T linear, while clear saturation is observed for H-c2,(a) (T), leading to a strongly temperature-dependent anisotropy parameter gamma. The linear shape of H-c2,(c) (T) is very similar to that observed in nodal KFe2As2, but very different from full-gap LiFeAs. Irradiation does not introduce any additional features on the H-c2(T) line corresponding to the matching field. Instead, it suppresses uniformly both T-c and H-c2, keeping their ratio constant.
