dc.description | A Bi<sub>2</sub>Sr<sub>2</sub>CaCu<sub>2</sub>O<sub>8+δ</sub> cross-whiskers junction has been successfully discovered as a novel intrinsic Josephson junction without using any technique for micro-fabrication. Two Bi<sub>2</sub>Sr<sub>2</sub>CaCu<sub>2</sub>O<sub>8+δ</sub> whisker crystals were placed crosswise on a MgO substrate and heated at 850 °C for 30 min. They were electrically connected at their c-planes. The measurement terminals were made at the four ends of the whiskers. The I-V characteristics of the cross-whiskers junction at 5 K were found to show a clear multiple-branch structure with a spacing of approximately 15 mV, which is a feature of an intrinsic Josephson junction. The critical current density J<sub>C</sub> was estimated to be 1170 A cm<sup>-2</sup>. The branch structure was strongly suppressed by a magnetic field above 1 kOe. |
