Description

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.
