Abstract(in English) | TFA-MOD (trifluoroacetate-metalorganic deposition) method is low cost non-vacuum coating process to obtain the thin film of superconductors with precise controllability of compositions. However, There was a possibility with micro-crack in YBa_2Cu_3O_7-δ(YBCO) film on the LaAlO_3 substrate. The YBCO film reliability is important in the microwave filter for the front-end which has already come in the practical stage of mobile telecommunication stations. The YBCO film on MgO can avoid the micro-crack, because the compressive stress is received by the MgO substrate. CeO_2 buffered layer must be inserted between YBCO film and MgO, because the TFA-MOD YBCO thin film preparation is indispensable in order to protect the fluorine reaction to the practically useful MgO substrate (2HF+MgO -> H_2O+MgF_2). The comparisons between TFA-MOD and PLD YBCO films on MgO substrates are reported on 22GHz surface resistance and critical current density characteristics. |
