Vortex lattice in two-dimensional chiral XY ferromagnets and the inverse Berezinskii-Kosterlitz-Thouless transition
A. Costa, M. B. Sturla
In this Letter we will show that, in the presence of a properly modulated Dzyaloshinskii-Moriya (DM) interaction, a vortex-antivortex lattice appears at low temperatures for…
Anomalous Josephson Hall effect charge and transverse spin currents in superconductor/ferromagnetic insulator/superconductor junctions
Andreas Costa, Jaroslav Fabian
Interfacial spin-orbit coupling in Josephson junctions offers an intriguing way to combine anomalous Hall and Josephson physics in a single device. We study theoretically how the s…
Skew Andreev reflection in ferromagnet/superconductor junctions
Andreas Costa, Alex Matos-Abiague, Jaroslav Fabian
Andreev reflection (AR) in ferromagnet/superconductor junctions is an indispensable spectroscopic tool for measuring spin polarization. We study theoretically how the presence of a…
Connection between zero-energy Yu-Shiba-Rusinov states and 0- transitions in magnetic Josephson junctions
Andreas Costa, Jaroslav Fabian, Denis Kochan
We study the bound state spectrum and 0- transitions in ballistic quasi-1D superconductor/ferromagnetic insulator/superconductor (S/FI/S) Josephson junctions. In addition to the…
