Research Abstract

We have succeeded in in-situ growth of epitaxial thin films of iron-pnictides, which are remarked as the second generation materials of high temperature superconductors. Optimally doped superconducting thin films are successfully grown by pulsed laser deposition (PLD) technique using exima laser. We have also grown single crystalline samples which complement the thin films and performed precise experiments on the physical properties of the obtained materials.
