Title Detection of discretized single-shell penetration in mesoscopic vortex matter Type Journal Article
Year 2014 Publication Journal of Physics: Conference Series Abbreviated Journal
Volume 568 Issue 2 Pages 022010
Keywords
Abstract We investigated configurational changes in mesoscopic vortex matter with less than thousand vortices during flux penetration in freestanding 50 μm diameter disks of Bi 2 Sr 2 CaCu 2 O 8+δ . High-resolution AC and DC local magnetometry data reveal oscillations in the transmittivity echoed in peaks in the third-harmonics magnetic signal fainting on increasing vortex density. By means of extra experimental evidence and a simple geometrical analysis we show that these features fingerprint the discretized entrance of single-shells of vortices having a shape that mimics the sample edge.
