- Abstract
- We used oxygen ion irradiation to transfer the nanoscale pattern of a porous alumina mask into high-TC superconducting thin films. This causes a nanoscale spatial modulation of superconductivity and strongly affects the magneto-transport below TC, which shows a series of periodic oscillations reminiscent of the Little–Parks effect in superconducting wire networks. This irradiation technique could be extended to other oxide materials in order to induce ordered nanoscale phase segregation.
