Strongly fluctuating moments in the high-temperature magnetic superconductor RbEuFeAs
K. Willa, R. Willa, J. -K. Bao +5
We report detailed specific heat measurements on the recently discovered magnetic superconductor RbEuFeAs. We investigated the superconducting transition at 37K and extract…
Nanocalorimetric Evidence for Nematic Superconductivity in the Doped Topological Insulator SrBiSe
Kristin Willa, Roland Willa, Kok Wee Song +6
Spontaneous rotational-symmetry breaking in the superconducting state of doped has attracted significant attention as an indicator for topological supe…
Thermal hysteresis of the Campbell response as a probe for bulk pinscape spectroscopy
Roland Willa, Mariano Marziali Bermúdez, Gabriela Pasquini
In type-II superconductors, the macroscopic response of vortex matter to an external perturbation depends on the local interaction of flux lines with the pinning landscape (pinscap…
Peak effect due to competing vortex ground states in superconductors with large inclusions
Roland Willa, Alexei E. Koshelev, Ivan A. Sadovskyy +1
Superconductors can support large dissipation-free electrical currents only if vortex lines are effectively immobilized by material defects. Macroscopic critical currents depend on…
Thermal depinning and creep in strong pinning theory
Martin Buchacek, Roland Willa, Vadim B. Geshkenbein +1
Pinning and thermal creep determine the response of numerous systems containing superstructures, e.g., vortices in type II superconductors, domain walls in ferroics, or dislocation…
