Abstract

Based on two-band Ginzburg-Landau theory, we study the upper critical fields for the overdoped composition of the iron-based superconductor Ba(Fe1-xNix)2As2 with x = 0.072. All the temperature and angular results of this compound are consistent with the experimental data. Thus our analysis strongly suggests that Ba(Fe1-xNix)2As2 in the overdoped regime is a two-gap superconductor. ? 2015, Polish Academy of Sciences.
