Planar scanning probe microscopy enables vector magnetic field imaging at the nanoscale
Paul Weinbrenner, Patricia Klar, Christian Giese +6
Planar scanning probe microscopy is a recently emerging alternative approach to tip-based scanning probe imaging. It can scan an extended planar sensor, such as a polished bulk dia…
Emission of coherent THz magnons in an antiferromagnetic insulator triggered by ultrafast spin-phonon interactions
E. Rongione, O. Gueckstock, M. Mattern +17
Antiferromagnetic materials have been proposed as new types of narrowband THz spintronic devices owing to their ultrafast spin dynamics. Manipulating coherently their spin dynamics…
Spin waves in coupled YIG/Co heterostructures
Stefan Klingler, Vivek Amin, Stephan Geprägs +9
We investigate yttrium iron garnet (YIG)/cobalt (Co) heterostructures using broadband ferromagnetic resonance (FMR). We observe an efficient excitation of perpendicular standing sp…
Spin Hall magnetoresistance in antiferromagnet/heavy-metal heterostructures
Johanna Fischer, Olena Gomonay, Richard Schlitz +8
We investigate the spin Hall magnetoresistance in thin film bilayer heterostructures of the heavy metal Pt and the antiferromagnetic insulator NiO. While rotating an external magne…
Spin Hall Magnetoresistance in a Canted Ferrimagnet
Kathrin Ganzhorn, Joseph Barker, Richard Schlitz +7
We study the spin Hall magnetoresistance effect in ferrimagnet/normal metal bilayers, comparing the response in collinear and canted magnetic phases. In the collinear magnetic phas…
Temperature dependent spin transport properties of Platinum inferred from spin Hall magnetoresistance measurements
Sibylle Meyer, Matthias Althammer, Stephan Geprägs +3
We study the temperature dependence of the spin Hall magnetoresistance (SMR) in yttrium iron garnet/platinum hybrid structures via magnetization orientation dependent magnetoresist…
