Superconducting oyxpnictide thin films — •Andreas Reisner¹, Martin Kidszun¹, Thomas Thersleff², Elke Reich¹, Bernhard Holzapfel¹, Ludwig Schultz¹, and Silvia Haindl¹ — ¹IFW Dresden, Institute of Metallic Materials, 01069 Dresden, Germany — ²Uppsala University, Angstrom Laboratory, Box 524, S-751 20 Uppsala, Sweden

We present an overview on the oxypnictide thin film preparation. So far, only LaAlO₃ (001) single crystalline substrates provided a successful growth using pulsed laser deposition in combination with a post annealing process. Further experiments on the in-situ deposition will be reported. The structure of the films was investigated by X-ray diffractometry and transmission electron microscopy. Transport properties were measured with different applied fields to obtain a magnetic phase diagram for this new type of superconductor.
