Collective vortex rectification effects in films with a periodic pinning array
Clecio C. de Souza Silva, J. Van de Vondel, B. Y. Zhu +2
The vortex ratchet effect has been studied in Al films patterned with square arrays of submicron antidots. We have investigated the transport properties of two sets of samples: (i)…

Vortex rectification effects in films with periodic asymmetric pinning
J. Van de Vondel, C. C. de Souza Silva, B. Y. Zhu +2
We study the transport of vortices excited by an ac current in an Al film with an array of nanoengineered asymmetric antidots. The vortex response to the ac current is investigated…
