Query: Strong field-matching effects in superconducting YBa2Cu3O7-{\delta}
  films with vortex energy landscapes engineered via masked ion irradiation   We have developed a masked ion irradiation technique to engineer the energy
landscape for vortices in oxide superconductors. This approach associates the
possibility to design the landscape geometry at the nanoscale with the unique
capability to adjust depth of the energy wells for vortices. This enabled us to
unveil the key role of vortex channeling in modulating the amplitude of the
field matching effects with the artificial energy landscape, and to make the
latter govern flux dynamics over an usually wide range of temperatures and
applied fields.
