Abstract

Epitaxial Fe-Te-Se thin films were deposited by pulsed laser deposition at 250-600°C on SrTiO ₃ (100), MgO (100), LaAlO ₃ (100) and CaF ₂ (100) single crystal substrates. The best superconducting film was grown on CaF ₂: K and K with T _dep=300°C and 3Hz. Critical current density J _c (T=4.2K) was 0.41×10 ⁶Acm ² at 0T and 0.23×10 ⁶Acm ² at 9T. The angular dependence of J _c shows a broad c-axis correlated peak when B3T.
