Abstract
The measurements on the magnetic image of interlayer vortices are performed for the high-Tc YBa2Cu3O7−y(110) thin film using a high sensitive scanning SQUID microscopy. Clear images of aligned giant interlayer vortices are observable. For the majority of vortices, using the London model, the c-axis penetration depth is estimated to be about 20μm at 3K. The temperature dependence of λc is obtained from the observed vortex images at different temperatures, whose behavior is in good agreement with those of the microwave cavity measurement.
