題名: | Nb lateral Josephson junctions induced by a NiFe cross strip | 作者: | Lin, L. K. ; Huang, S. Y. ; Huang, J. H. ; Lee, S. F. 李尚凡 |

Transport measurements on the Nb lateral junctions exhibit modulations of the critical current with a varying perpendicular magnetic field similar to a Fraunhofer interference pattern, which demonstrates the dc Josephson effect. The modulations of the critical current could be attributed to an effective weak link embedded in the Nb strip and formed a Josephson junction. Appearance of Shapiro steps on the current-voltage curves of these junctions when microwaves irradiation is applied proves the ac Josephson effect. The underlying physics of the effective weak link induced by the NiFe strip is discussed. | 關聯: | Applied Physics Letters, 101(24), 242601 | 資料來源: | http://dx.doi.org/10.1063/1.4770302 | 資料類型: | article |
