Optimizing the spin-pumping induced inverse spin Hall voltage by crystal growth in Fe/Pt bilayers
Evangelos Th. Papaioannou, Philipp Fuhrmann, Matthias B. Jungfleisch +5
We examine the influence of crystal growth on the spin-pumping induced inverse spin Hall effect in Fe/Pt bilayers. The morphology of the Fe/Pt interface influences the effective sp…
Sub-microsecond fast temporal evolution of the spin Seebeck effect
M. Agrawal, V. I. Vasyuchka, A. A. Serga +7
We present temporal evolution of the spin Seebeck effect in a YIG|Pt bilayer system. Our findings reveal that this effect is a sub-microseconds fast phenomenon governed by the temp…
Thickness and power dependence of the spin-pumping effect in Y3Fe5O12/Pt heterostructures measured by the inverse spin Hall effect
M. B. Jungfleisch, A. V. Chumak, A. Kehlberger +6
The dependence of the spin-pumping effect on the yttrium iron garnet (Y3Fe5O12, YIG) thickness detected by the inverse spin Hall effect (ISHE) has been investigated quantitatively.…
Determination of the origin of the spin Seebeck effect - bulk vs. interface effects
Andreas Kehlberger, René Röser, Gerhard Jakob +9
The observation of the spin Seebeck effect in insulators has meant a breakthrough for spin caloritronics due to the unique ability to generate pure spin currents by thermal excitat…
Optimization of the yttrium iron garnet/platinum interface for spin pumping-based applications
M. B. Jungfleisch, V. Lauer, R. Neb +2
The dependence of the spin pumping efficiency and the spin mixing conductance on the surface processing of yttrium iron garnet (YIG) before the platinum (Pt) deposition has been in…
