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…
Transverse spin Seebeck vs. Anomalous and Planar Nernst Effects in Permalloy Thin Films
M. Schmid, S. Srichandan, D. Meier +6
Transverse magneto-thermoelectric effects are studied in permalloy thin films grown on MgO and GaAs substrates and compared to those grown on suspended SiN membranes. The transvers…
Influence of heat flow directions on Nernst effects in Py/Pt bilayers
Daniel Meier, Daniel Reinhardt, Maximilian Schmid +4
We investigated the voltages obtained in a thin Pt strip on a Permalloy film which was subject to in-plane temperature gradients and magnetic fields. The voltages detected by thin…
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…
Thermally driven spin and charge currents in thin NiFe2O4/Pt films
Daniel Meier, Timo Kuschel, Liming Shen +6
We present results on the longitudinal spin Seebeck effect (LSSE) shown by semiconducting ferrimagnetic NiFe2O4/Pt films from room temperature down to 50K base temperature. To the…
