Abstract(in English) | We have previously reported on an acid-treatment process for the fabrication of Bi_2Sr_2CaCu_2O_x (Bi-2212) stacks. In this process, we found interesting phenomena that Bi-2212 single crystal dipped into acid solution of pH>1.4 was varied to transparent material. In this study, we tried to fabricate dc-SQUID with an in-plane loop having two stacks of IJJs by this acid-treatment process. The SQUID showed large hysteretic current-voltage characteristics at liquid N_2 temperature. The SQUIDs showed periodic modulation of the critical current I_c (B) as a function of magnetic field, but had poor batch-to-batch reproducibility. Although there are many problems to be solved, the proposed acid treatment process may be useful for dc-SQUID based on Bi-2212 IJJs. |
