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…
Co-sputtered PtMnSb thin films and PtMnSb/Pt bilayers for spin-orbit torque investigations
Jan Krieft, Johannes Mendil, Myriam H. Aguirre +7
The manipulation of the magnetization by spin-orbit torques (SOTs) has recently been extensively studied due to its potential for efficiently writing information in magnetic memori…
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…
Static magnetic proximity effect in Pt/NiFe bilayers investigated by x-ray resonant magnetic reflectivity
Christoph Klewe, Timo Kuschel, Jan-Michael Schmalhorst +6
We present x-ray resonant magnetic reflectivity (XRMR) as a very sensitive tool to detect proximity induced interface spin polarization in Pt/Fe, Pt/NiFe, Pt/Ni$_{81}…
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…
Longitudinal spin Seebeck effect contribution in transverse spin Seebeck effect experiments in Pt/YIG and Pt/NFO
Daniel Meier, Daniel Reinhardt, Michael van Straaten +10
We investigate the inverse spin Hall voltage of a 10nm thin Pt strip deposited on the magnetic insulators Y3Fe5O12 (YIG) and NiFe2O4 (NFO) with a temperature gradient in the film p…
Static magnetic proximity effect in Pt/NiFe2O4 and Pt/Fe bilayers investigated by x-ray resonant magnetic reflectivity
Timo Kuschel, Christoph Klewe, Jan-Michael Schmalhorst +11
The spin polarization of Pt in Pt/NiFe2O4 and Pt/Fe bilayers is studied by interface-sensitive x-ray resonant magnetic reflectivity to investigate static magnetic proximity effects…
Physical characteristics and cation distribution of NiFe2O4 thin films with high resistivity prepared by reactive co-sputtering
Christoph Klewe, Markus Meinert, Alexander Boehnke +6
We fabricated NiFe2O thin films on MgAl2O4 (001) substrates by reactive dc magnetron co-sputtering in a pure oxygen atmosphere at different substrate temperatures. The film propert…
Quantitative study of the spin Hall magnetoresistance in ferromagnetic insulator/normal metal hybrids
Matthias Althammer, Sibylle Meyer, Hiroyasu Nakayama +18
We experimentally investigate and quantitatively analyze the spin Hall magnetoresistance effect in ferromagnetic insulator/platinum and ferromagnetic insulator/nonferromagnetic met…
Negative spin polarization of Mn2VGa probed by tunnel magnetoresistance
Christoph Klewe, Markus Meinert, Jan Schmalhorst +1
The ferrimagnetic Heusler compound Mn2VGa is predicted to have a pseudogap in the majority spin channel, which should lead to a negative tunnel magnetoresistance. We synthesized ep…
