CRITICAL CURRENT DEPENDENCE OF STACKED JOSEPHSON JUNCTIONS DC SQUID IN Bi₂Sr₂CaCu₂O_8+Δ
- SANG-JAE KIM
International Journal of Modern Physics B30 Jul 2007
Preview Abstract
We investigate critical current (I_c) modulation of stacked Josephson junctions (SJJs) dc superconducting quantum interference device (dc SQUID) on a Bi₂Sr₂CaCu₂O_8+δ (Bi-2212) whisker. A coupled SJJs with a completely perforated hole of 0.1 μm × 0.2 μm were fabricated by using a 3-D focused-ion-beam (FIB) etching method. Those dc SQUIDs exhibited uniform multi-branch structures and clearly oscillated critical current under external magnetic fields (H_e). With applying H_e, the clear periodic modulation patterns of I_c are obtained and well fitted to the calculated value from the loop area of 0.02 μm².
