| Outline of Final Research Achievements |
In this research, 0212 samples show overdoped states after the high pressure synthesis and annealing under ambient pressure can decrease the oxygen content. In the annealed samples, the slope in temperature dependence of Hirr is increased, which is larger than that of Bi-2212, even though the Tc value is almost constant. Furthermore, growth conditions for 0223 crystals are realized. From these results, it is concluded that intrinsic Josephson junction devices can be made with 02(n-1)n crystals.
