Electrical transport and optical band gap of NiFeO thin films
Panagiota Bougiatioti, Orestis Manos, Christoph Klewe +5
We fabricated NiFeO thin films on MgAlO(001) substrates by reactive dc magnetron co-sputtering varying the oxygen partial pressure during depositi…
Quantitative disentanglement of spin Seebeck, proximity-induced and intrinsic anomalous Nernst effect in NM/FM bilayers
Panagiota Bougiatioti, Christoph Klewe, Daniel Meier +8
We identify and investigate thermal spin transport phenomena in sputter-deposited Pt/NiFeO () bilayers. We separate the voltage generated by th…
Longitudinal spin Seebeck coefficient: heat flux vs. temperature difference method
A. Sola, P. Bougiatioti, M. Kuepferling +5
The determination of the longitudinal spin Seebeck effect (LSSE) coefficient is currently plagued by a large uncertainty due to the poor reproducibility of the experimental conditi…
Quantitative separation of the anisotropic magnetothermopower and planar Nernst effect by the rotation of an in-plane thermal gradient
Oliver Reimer, Daniel Meier, Michel Bovender +9
A thermal gradient as the driving force for spin currents plays a key role in spin caloritronics. In this field the spin Seebeck effect (SSE) is of major interest and was investiga…
Temperature dependence of the spin Hall angle and switching current in the nc-W(O)/CoFeB/MgO system with perpendicular magnetic anisotropy
Lukas Neumann, Daniel Meier, Jan Schmalhorst +3
We investigated the temperature dependence of the switching current for a perpendicularly magnetized CoFeB film deposited on a nanocrystalline tungsten film with large oxygen conte…
Static Magnetic Proximity Effect in Pt Layers on Sputter-Deposited NiFe2O4 and on Fe of Various Thicknesses Investigated by XRMR
Timo Kuschel, Christoph Klewe, Panagiota Bougiatioti +7
The longitudinal spin Seebeck effect is detected in sputter-deposited NiFe2O4 films using Pt as a spin detector and compared to previously investigated NiFe2O4 films prepared by ch…
Detection of DC currents and resistance measurements in longitudinal spin Seebeck effect experiments on Pt/YIG and Pt/NFO
Daniel Meier, Timo Kuschel, Sibylle Meyer +5
In this work we investigated thin films of the ferrimagnetic insulators YIG and NFO capped with thin Pt layers in terms of the longitudinal spin Seebeck effect (LSSE). The electric…
Dependence of transverse magneto-thermoelectric effects on inhomogeneous magnetic fields
A. S. Shestakov, M. Schmid, D. Meier +2
Transverse magneto-thermoelectric effects are studied in permalloy thin films grown on MgO substrates. We find that small parasitic magnetic fields below 1 Oe can produce artifacts…
Sign change in the tunnel magnetoresistance of Fe3O4/MgO/Co-Fe-B magnetic tunnel junctions depending on the annealing temperature and the interface treatment
Luca Marnitz, Karsten Rott, Stefan Niehörster +12
Magnetite (Fe3O4) is an eligible candidate for magnetic tunnel junctions (MTJs) since it shows a high spin polarization at the Fermi level as well as a high Curie temperature of 58…
