2000年7月1日 · Our data suggest that the magnetic flux can be generated in the superconductive YBCO loop without phase transition at the any part of the loop, and the mechanism is attributed to the ultrafast optical supercurrent modulation.

2018年2月14日 · This paper presents modification for a model to retrace magnetic hysteresis loop and calculate hysteresis energy loss (HEL) in YBa 2 Cu 3 O 7 (YBCO). In comparison with reported experimental results, it is revealed that the modified model could retrace successfully magnetic hysteresis loop for YBCO.

2002年2月15日 · In the present work, we demonstrate the magnetic flux generation in the YBCO thin-film loop by selected fs optical pulses and semi-quantitatively evaluate φ by means of THz radiation imaging. Recently, we developed the THz radiation imaging system to visualize supercurrent distributions in YBCO thin films [13].

We studied magnetic flux generation in a YBCO thin film loop by optical modulation of the shielding current induced by an external magnetic field with femtosecond (fs) laser pulses. The magnetic flux was successfully created in the loop and visualized by the...
