Event Description Goran Karapetrov, PhD, Drexel University
Superconductors are one of the few materials that exhibit coherent electron behavior on macroscopic distances. As the size of the superconductor shrinks, the behavior of the superconducting Cooper pairs begins to reveal the intrinsic nature of the Bose condensate. Today’s scanning probe microscopy and spectroscopy tools allow us to image the spatial modulation of the superconducting condensate with atomic precision. In this talk I will show how one can explore the rich physics of superconductors on the example of magnetically coupled superconductor-ferromagnet hybrids. Ferromagnet materials are used as a template that modulates the superconducting order parameter on nanometer scale. As we change the external parameters such as temperature and magnetic field, we can track the evolution of superconductivity in these templated systems. In the process we have an opportunity to find clues about the superconductor itself and the new ways to control the behavior of the superconductors on the nanoscale. |
