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.

我们成功地原位生长了被誉为第二代高温超导体材料的铁镍化合物外延薄膜。利用脉冲激光沉积(PLD)技术，利用EXIMA激光，成功地制备了最佳掺杂超导薄膜。我们还生长了补充薄膜的单晶样品，并对所获得的材料的物理性质进行了精确的实验。
