Abstract

Single-crystalline films of superconducting Sr_1-xK_xFe₂As₂ and Ba_1-xK_xFe₂As₂ were grown by molecular beam epitaxy (MBE). The most crucial problem in MBE growth of these compounds is the high volatility of elemental K. The key to incorporating K into films is low-temperature growth (≤ 350°C) in reduced As flux. We performed a systematic study of the doping dependence of T_c in Ba_1-xK_xFe₂As₂ for x = 0.0 to 1.0. The highest T_c^on (T_c^end) so far attained for Ba_1-xK_xFe₂As₂ is 38.3 K (35.5 K) at x ∼ 0.3.
