Interaction of Skyrmions and Pearl Vortices in Superconductor-Chiral Ferromagnet Heterostructures
Samme M. Dahir, Anatoly F. Volkov, Ilya M. Eremin
We investigate a hybrid heterostructure with magnetic skyrmions (Sk) inside a chiral ferromagnet interfaced by a thin superconducting film via an insulating barrier. The barrier pr…
Emerging superconductivity with broken time reversal symmetry inside a superconducting -wave state
V. Grinenko, R. Sarkar, K. Kihou +17
In general, magnetism and superconductivity are antagonistic to each other. However, there are several families of superconductors, in which superconductivity may coexist with magn…
Short-time dynamics in -wave superconductor with incipient bands
Marvin A. Müller, Pengtao Shen, Maxim Dzero +1
Motivated by the recent observation of the time-reversal symmetry broken state in K-doped BaFeAs superconducting alloys, we theoretically study the collective modes and the…
Fluctuation-induced Néel and Bloch skyrmions at topological insulator surfaces
Flavio S. Nogueira, Ilya Eremin, Ferhat Katmis +3
Ferromagnets in contact with a topological insulator have become appealing candidates for spintronics due to the presence of Dirac surface states with spin-momentum locking. Becaus…
In-plane magnetic penetration depth of superconducting CaKFeAs
Rustem Khasanov, William R. Meier, Yun Wu +7
The temperature dependence of the in-plane magnetic penetration depth () in an extensively characterized sample of superconducting CaKFeAs ( K) w…
