Title: Tuning the patterns of the Fulde-Ferrell-Larkin-Ovchinnikov state by magnetic impurities in <i>d</i> -wave superconductors
Abstract: A local structure transition in the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state from checkerboard to stripe pattern induced by magnetic impurities is computationally observed in near-optimally doped d-wave superconductors. In the absence of impurities, the checkerboard pattern of the FFLO state is energetically favorable under a parallel field, while a local structure transition to the stripe pattern occurs when strong magnetic impurities are inserted. This finding provides an avenue to tune the patterns of the FFLO state, and is ready to be checked by neutron scattering and nuclear magnetic resonance experiments. The implication for high-Tc cuprate superconductors is discussed.
