Singlet-triplet conversion and the long-range proximity effect in superconductor-ferromagnet structures with generic spin dependent fields.
The long-range proximity effect in superconductor-ferromagnet (S/F) hybrid nanostructures is observed if singlet Cooper pairs from the superconductor are converted into triplet pairs which can diffuse into the ferromagnet over large distances. It is commonly believed that this happens only in the presence of magnetic inhomogeneities. We show that there are other sources of the long-range triple...
متن کاملQuantitative Disentanglement of Spin Seebeck, Proximity-Induced, and Ferromagnet-Induced Anomalous Nernst Effect in Normal-Metal–Ferromagnet Bilayers
We fabricated thin films by co-sputter deposition [1] starting from pure high-resistive NiFe2O4 (NFO) (∼ 160 nm) up to the metallic Ni33Fe67 (10.4 nm) with intermediate NiFe2Ox1 (60 nm) and NiFe2Ox2 (35 nm), with 4 > x1 > x2 > 0. The films were deposited on MgAl2O4(001) (MAO) substrates by dc magnetron sputtering. The metallic film was deposited in Ar atmosphere with pressure in the range of 2 ...
متن کاملOdd Triplet Superconductivity and Related Phenomena in Superconductor-Ferromagnet Structures
We consider novel unusual effects in superconductor-ferromagnet (S/F) structures. In particular we analyze the triplet component (TC) of the condensate generated in those systems.This component is odd in frequency and even in the momentum, which makes it insensitive to non-magnetic impurities. If the exchange field is not homogeneous in the system the triplet component is not destroyed even by ...

متن کاملQuantitative Disentanglement of the Spin Seebeck, Proximity-Induced, and Ferromagnetic-Induced Anomalous Nernst Effect in Normal-Metal-Ferromagnet Bilayers.
We identify and investigate thermal spin transport phenomena in sputter-deposited Pt/NiFe_{2}O_{x} (4≥x≥0) bilayers. We separate the voltage generated by the spin Seebeck effect from the anomalous Nernst effect (ANE) contributions and even disentangle the ANE in the ferromagnet (FM) from the ANE produced by the Pt that is spin polarized due to its proximity to the FM. Further, we probe the depe...
