Low Temperature Suppression of the Spin Nernst Angle in Pt
Tobias Wimmer, Janine Gückelhorn, Sebastian Wimmer +7
We demonstrate the low temperature suppression of the platinum (Pt) spin Nernst angle in bilayers consisting of the antiferromagnetic insulator hematite (-FeO) and Pt up…
Observation of Antiferromagnetic Magnon Pseudospin Dynamics and the Hanle effect
Tobias Wimmer, Akashdeep Kamra, Janine Gückelhorn +5
We report on experiments demonstrating coherent control of magnon spin transport and pseudospin dynamics in a thin film of the antiferromagnetic insulator hematite utilizing two Pt…
Spin transport in a magnetic insulator with zero effective damping
Tobias Wimmer, Matthias Althammer, Lukas Liensberger +5
Applications based on spin currents strongly profit from the control and reduction of their effective damping and their transport properties. We here experimentally observe magnon…
Investigation of induced Pt magnetic polarization in Pt/Y3Fe5O12 bilayers
Stephan Geprägs, Sibylle Meyer, Stephan Altmannshofer +5
Using X-ray magnetic circular dichroism (XMCD) measurements, we explore the possible existence of induced magnetic moments in thin Pt films deposited onto the ferrimagnetic insulat…
