Charge dynamics in spintronic THz emitters
Georg Schmidt, Bikash Das-Mohapatra, Evangelos Th. Papaioannou
We show that to correctly describe the ultrafast currents in spintronic THz emitters it is necessary to take charge equilibration into account. The charge current which is locally…
Enhancement of spin mixing conductance in LaSrMnO/LaNiO/SrRuO heterostructures
Christoph Hauser, Camillo Ballani, Philipp Dürrenfeld +5
We investigate spin pumping and the effective spin mixing conductance in heterostructures based on magnetic oxide trilayers composed of LaSrMnO (LSMO), LaNiO$_3…
Modification of spintronic terahertz emitter performance through defect engineering
Dennis M. Nenno, Laura Scheuer, Dominik Sokoluk +10
Spintronic ferromagnetic/non-magnetic heterostructures are novel sources for the generation of THz radiation based on spin-to-charge conversion in the layers. The key technological…
Determination of the spin Hall angle in single-crystalline Pt films from spin pumping experiments
Sascha Keller, Laura Mihalceanu, Matthias R. Schweizer +12
We report on the determination of the spin Hall angle and the identification of the role of the interface roughness for the inverse spin Hall effect (ISHE) in ultra-clean, defect-r…
A Microscopic Explanation of Microwave Spin Pumping
John F. Gregg, Burkard Hillebrands, Alistair Inglis +4
We contend that Microwave Spin Pumping was first predicted and observed - albeit using a different and more sensitive detection mechanism than Inverse Spin Hall Effect - in the 195…
Spin-pumping through a varying-thickness MgO interlayer in Fe/Pt system
Laura Mihalceanu, Sascha Keller, Jochen Greser +7
The spin-pumping mechanism is probed through a tunnelling MgO interlayer in Fe/Pt bilayers. We show by ferromagnetic resonance technique and spin-pumping experiments that spin curr…
Relative weight of the inverse spin Hall and spin rectification effects for metallic Py,Fe/Pt and insulating YIG/Pt bilayers estimated by angular dependent spin pumping measurements
Sascha Keller, Jochen Greser, Matthias R. Schweizer +3
We quantify the relative weight of inverse spin Hall and spin rectification effects occurring in RF-sputtered polycrystalline permalloy, molecular beam epitaxy-grown epitaxial iron…
Lack of correlation between the spin mixing conductance and the ISHE-generated voltages in CoFeB/Pt,Ta bilayers
A. Conca, B. Heinz, M. R. Schweizer +3
We investigate spin pumping phenomena in polycrystalline CoFeB/Pt and CoFeB/Ta bilayers and the correlation between the effective spin mixing conductance $g^{\uparrow\downarrow}_{\…
Bose-Einstein Condensation of Quasi-Particles by Rapid Cooling
M. Schneider, T. Brächer, D. Breitbach +18
The fundamental phenomenon of Bose-Einstein Condensation (BEC) has been observed in different systems of real and quasi-particles. The condensation of real particles is achieved th…
Thickness dependent enhancement of the polar magneto-optic Kerr effect in Co magnetoplasmonic nanostructures
Richard M. Rowan-Robinson, Emil Melander, Ioan-Augustin Chioar +4
Large surface plasmon polariton assisted enhancement of the magneto-optical activity has been observed in the past, through spectral measurements of the polar Kerr rotation in Co h…
Light localisation and magneto-optic enhancement in Ni anti-dot arrays
Markus Rollinger, Philip Thielen, Emil Melander +6
The excitation of surface plasmons in magnetic nano-structures can strongly influence their magneto-optical properties. Here, we use photoemission electron microscopy to map the sp…
Microwave-induced spin currents in ferromagnetic-insulator|normal-metal bilayer system
Milan Agrawal, Alexander A. Serga, Viktor Lauer +3
A microwave technique is employed to simultaneously examine the spin pumping and the spin Seebeck effect processes in a YIG|Pt bilayer system. The experimental results show that fo…
Melting artificial spin ice
Vassilios Kapaklis, Unnar B. Arnalds, Adam Harman-Clarke +7
Artificial spin ice arrays of micromagnetic islands are a means of engineering additional energy scales and frustration into magnetic materials. Despite much progress in elucidatin…
Magnetooptic enhancement and magnetic properties in Fe antidot films with hexagonal symmetry

The magnetooptic and magnetic properties of hexagonal arrays of holes in optically thin iron films are presented. We analyze their dependence on the hole radius and compare the res…
