Pair-breaking in iron-pnictides

Abstract

The puzzling features of the slopes of the upper critical field at the critical temperature $T_c$, $H_{c2}^{\prime }(T_c)\propto T_c$, and of the specific heat jump $\Delta C\propto T_c^3$ of iron-pnictides are interpreted as caused by a strong pair-breaking.
