| Abstract(in English) | In order to study the intrinsic noise in direct-coupled high-Tc SQUIDs induced by a shielding current, we measured the low-frequency flux noise of a narrow current-carrying YBCO strip. In addition to the residual noise after the strip became flux-creep to -flow state by the current, reversible noise was observed during the application of current but disappeared when the current was removed. The threshold current for the reversible noise was lower than that for the flux-creep, being depend on the fabrication process of the strip. The sources of the two types of low-frequency flux noise were discussed on the bases of existing models of vortex penetration into and pinning in a superconducting thin-film.. |
