Commensurability effects in superconducting Nb films with quasiperiodic pinning arrays.
We study experimentally the critical depinning current I(c) versus applied magnetic field B in Nb thin films which contain 2D arrays of circular antidots placed on the nodes of quasiperiodic (QP) fivefold Penrose lattices. Close to the transition temperature T(c) we observe matching of the vortex lattice with the QP pinning array, confirming essential features in the I(c)(B) patterns as predict...
متن کاملTemperature dependent pinning phenomenon in superconducting Nb films with triangular and honeycomb pinning arrays.
The pinning phenomena in superconducting Nb films with triangular and honeycomb pinning arrays were explored. Special temperature dependent phenomena were found for both films. For the film with a triangular pinning array, the pronounced matching peaks in the critical currents as a function of magnetic field reduce from six to three within a narrow temperature range. This temperature dependent ...
متن کاملCommensurability and strong vortex pinning in nanopatterned Nb films
We present a study combining magnetization measurements and direct magneto-optical flux imaging on Nb films, which contain periodic arrays of nanoholes and have been grown on anodized aluminum oxide (AAO) substrates. The magnetization measurements reveal pronounced matching effects in the critical current over the entire temperature range from 4.2 K to Tc. The flux images do not reveal signatur...
متن کاملCommensurability effects in magnetic properties of superconducting Nb thin films with periodic submicrometric pores
Pinning properties in 100nm thick continuous and porous superconducting Nb films are examined by ac susceptibility and dc magnetization measurements. The Nb filmwas deposited on a smooth Si substrate, while the porous film, NbP , was deposited on an anodized Al oxide substrate. Pores or ‘‘antidots’’ 40 nm in diameter, 100 nm apart, form a triangular array. The porous film presents commensurate ...
متن کاملVortex lattice channeling effects in Nb films induced by anisotropic arrays of mesoscopic pinning centers
Rectangular arrays of Ni dots with small interdot separation have been fabricated in superconducting Nb films. The geometry of these rectangular arrays defines deep pinning potential channels. Two effects have been observed. ~i! When the vortices move perpendicular to the channels ~i.e., along the long side of the rectangular array! an enhancement of the background pinning is observed, as predi...
