Imaging anisotropic vortex dynamics in FeSe
Imaging anisotropic vortex dynamics in FeSe
Strong vortex pinning in FeSe could be useful for technological applications and could provide clues about the coexistence of superconductivity and nematicity. To characterize the pinning of individual, isolated vortices, we simultaneously apply a local magnetic field and image the vortex motion with scanning superconducting quantum interference devices susceptibility. We …
