| Research Abstract |
The high temperature oxide superconducting films are usually prepared by the sputtering and so on using expensive and large-scale apparatus. We have studied inexpensive preparation methods by using metal organic decomposition (MOD). After Bi_2Sr_2CaCu_2O_<8+x> (Bi-2212) thin films were prepared by the MOD method with the use of a commercial metal organic (MO) solution, we studied a preparation method using original suspensions as the solutions. Finally, Bi-2212 thin films prepared by using the original suspensions showed superconductivity, the intrinsic junction by a mesa structure, and a flatness indicating an ability of a interface junction.
