Inverse proximity effect and influence of disorder on triplet supercurrents in strongly spin-polarized ferromagnets
Roland Grein, Tomas Lofwander, Matthias Eschrig
We discuss the Josephson effect in strongly spin-polarized ferromagnets where triplet correlations are induced by means of spin-active interface scattering, extending our earlier w…
Superconducting proximity effect in semiconductor thin films with spin-splitting and spin-orbit interaction
Jens Michelsen, Roland Grein
Superconducting heterostructures with spin-active materials have emerged as promising platforms for engineering topological superconductors featuring Majorana bound states at surfa…
The effect of spin fluctuations on the electronic structure in iron based superconductors
Andreas Heimes, Roland Grein, Matthias Eschrig
Magnetic inelastic neutron scattering (INS) studies of iron-based superconductors reveal a strongly temperature-dependent spin-fluctuation spectrum in the normal conducting state,…
A Numerical Study of the Superconducting Proximity Effect in Topological Surface States
Roland Grein, Jens Michelsen, Matthias Eschrig
We study the superconducting proximity effect induced in the surface states of the 3-d topological insulator BiSe by a singlet, s-wave superconductor deposited on its surfa…
Electronic dispersion anomalies in the iron pnictide superconductor Ba_{1-x}K_xFe_2As_2
Andreas Heimes, Roland Grein, Matthias Eschrig
The pairing mechanism in the iron-pnictide superconductors is still unknown. However, similarities to the cuprate high-temperature superconductors suggest that a similar mechanism…
Is CrO Fully Spin-Polarized? - Analysis of Andreev Spectra and Excess Current
Tomas Lofwander, Roland Grein, Matthias Eschrig
We report an extensive theoretical analysis of point-contact Andreev reflection data available in literature on ferromagnetic CrO. We find that the spectra can be well understo…
