Resonant current-in-plane spin-torque diode effect in magnetnormal metal bilayers
Ulli Gems, Oliver Franke, Piet W. Brouwer
Via the spin-Hall effect and its inverse, in-plane charge currents in a normal metalferromagnet (NF) bilayer can be used to excite and detect magnetization dynamics in F. Usi…
Theory of nonlinear magnetoelectric transport effects in normal-metal magnetic-insulator heterostructures
Oliver Franke, Piet W. Brouwer
Heterostructures of normal metals (N) and magnetic insulators (F) show paradigmatic effects, such as spin-Hall magnetoresistance and electric drag currents. These effects are linea…
Femtosecond signatures of optically induced magnons before ultrafast demagnetization
Reza Rouzegar, Oliver Franke, Gal Lemut +8
Optically induced demagnetization of 3d metallic ferromagnets proceeds as fast as ~100 fs and is a crucial prerequisite for spintronic applications, such as ultrafast magnetization…
Observation of Ultrafast Coherent and Incoherent Spin Torques via Terahertz Spin-Hall Magnetoresistance
P. Kubaščík, R. Schlitz, O. Gueckstock +19
Spin Hall magnetoresistance (SMR) is a cornerstone effect in spintronics, enabling the electrical readout of magnetic states through spin-orbit coupling at interfaces. Despite its…
Hallmarks of terahertz magnon currents in an antiferromagnetic insulator
Hongsong Qiu, Oliver Franke, Yuanzhe Tian +11
The efficient transport of spin angular momentum is expected to play a crucial role in future spintronic devices, which potentially operate at frequencies reaching the terahertz ra…
Magnon-mediated electric current drag and nonlocal spin-Peltier effect in the ac regime
Oliver Franke, Duje Akrap, Piet W. Brouwer
Electron-magnon coupling at the interface between a normal metal and a magnetically ordered insulator modifies the electrical conductivity of the normal metal, an effect known as s…
Accessing ultrafast spin-transport dynamics in copper using broadband terahertz spectroscopy
Jiří Jechumtál, Reza Rouzegar, Oliver Gueckstock +10
We study the spatiotemporal dynamics of ultrafast electron spin transport across nanometer-thick copper layers using broadband terahertz spectroscopy. Our analysis of temporal dela…
