Charge, heat, and spin transport phenomena in metallic conductors
Nynke Vlietstra, Sebastian T. B. Goennenwein, Rudolf Gross +1
In solid state materials, gradients of the electro-chemical potential, the temperature, or the spin-chemical potential drive the flow of charge, heat, and spin angular momentum, re…
All-electrical detection of skyrmion lattice state and chiral surface twists
A. Aqeel, M. Azhar, N. Vlietstra +6
We study the high-temperature phase diagram of the chiral magnetic insulator CuOSeO by measuring the spin-Hall magnetoresistance (SMR) in a thin Pt electrode. We find disti…

Johanna Fischer, Matthias Althammer, Nynke Vlietstra +5
We investigate the spin Hall magnetoresistance (SMR) at room temperature in thin film heterostructures of antiferromagnetic, insulating, (0001)-oriented alpha-Fe2O3 (hematite) and…
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…
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…
Non-local magnon transport in the compensated ferrimagnet GdIG
Kathrin Ganzhorn, Tobias Wimmer, Joseph Barker +8
We study the diffusive transport of magnons through the compensated ferrimagnetic insulator Gd3Fe5O12 (GdIG). The magnons are injected and detected electrically in a non-local meas…
Influence of yttrium iron garnet thickness and heater opacity on the nonlocal transport of electrically and thermally excited magnons
Juan Shan, Ludo J. Cornelissen, Nynke Vlietstra +4
We studied the nonlocal transport behavior of both electrically and thermally excited magnons in yttrium iron garnet (YIG) as a function of its thickness. For electrically injected…
Electrical detection of spiral spin structures in Pt|Cu_2OSeO_3 heterostructures
A. Aqeel, N. Vlietstra, A. Roy +3
The interaction between the itinerant spins in metals and localized spins in magnetic insulators thus far has only been explored in collinear spin systems, such as garnets. Here, w…
Detection of spin pumping from YIG by spin-charge conversion in a Au/NiFe spin-valve structure
Nynke Vlietstra, Fasil K. Dejene, Bart J. van Wees
Many experiments have shown the detection of spin-currents driven by radio-frequency spin pumping from yttrium iron garnet (YIG), by making use of the inverse spin-Hall effect, whi…
