超导-磁性-超导约瑟夫森结数据集

超导-磁性-超导约瑟夫森结数据主要是对磁性约瑟夫森结的微分电导谱展开研究。利用输运测量技术，观察到了Fraunhofer patterns和Fiske step，证明了器件的高界面质量。并利用Origin对数据进行分析处理，探测到了0-Π约瑟夫森结的迹象和SQUID器件中的非平凡基态相位，证明在该结构中可存在磁交换作用导致的π相位耦合。本数据集主要记录了不同磁场下的超导输运实验数据，数据量3.64MB。The Superconductor-Magnet-Superconductor Josephson Junction dataset primarily focuses on the differential conductance spectroscopy of magnetic Josephson junctions. Using transport measurement techniques, Fraunhofer patterns and Fiske steps were observed, confirming the high interfacial quality of the devices. Data analysis and processing were conducted with Origin, which detected the signatures of 0-π Josephson junctions and non-trivial ground state phases in SQUID devices, proving that π-phase coupling induced by magnetic exchange interactions can exist in this structure. This dataset mainly records superconducting transport experimental data under various magnetic fields, with a total size of 3.64 MB.
