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…
Finite-frequency admittance and noise of a helical edge coupled to a magnet
Oliver Franke, Paula Koll, Peter G. Silvestrov +1
The exchange coupling of the helical edge state of a quantum spin-Hall insulator with an easy-plane magnet has no effect on its DC electrical conductance if the magnet's anisotropy…
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…
Observation of terahertz spin-Hall magnetoresistance in the model system
P. KubaÅ¡ÄÃk, R. Schlitz, O. Gueckstock +17
We report the observation of spin Hall magnetoresistance (SMR) in prototypical bilayers of ferrimagnetic yttrium iron garnet (YIG) and platinum in the frequency range from 0 THz to…
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…
