Enhanced vortex pinning by a composite antidot lattice in a superconducting Pb film
A. V. Silhanek, L. Van Look, R. Jonckheere +3
The use of artificial defects is known to enhance the superconducting critical parameters of thin films. In the case of conventional superconductors, regular arrays of submicron ho…
Dendritic flux penetration in Pb films with a periodic array of antidots
M. Menghini, R. J. Wijngaarden, A. V. Silhanek +2
We explore the flux-jump regime in type-II Pb thin films with a periodic array of antidots by means of magneto-optical measurements. A direct visualization of the magnetic flux dis…
Experimental determination of the number of flux lines trapped by micro-holes in superconducting samples
A. V. Silhanek, S. Raedts, M. J. Van Bael +1
The influence of a periodic landscape of pinning sites on the vortex dynamics in Pb thin films is explored by ac-susceptibility measurements. For different amplitudes h of the ac-d…
Paramagnetic reentrance of the ac-screening: Evidence of vortex avalanches in Pb thin films
A. V. Silhanek, S. Raedts, V. V. Moshchalkov
We have studied the influence of a square array of pinning centers on the dynamics of vortex avalanches in Pb thin films by means of ac- and dc- magnetization measurements. Close t…
Flux pinning properties of superconductors with an array of blind holes
S. Raedts, A. V. Silhanek, M. J. Van Bael +1
We performed ac-susceptibility measurements to explore the vortex dynamics and the flux pinning properties of superconducting Pb films with an array of micro-holes (antidots) and n…
