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…
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…
Operator Spreading in Random Unitary Circuits with Unitary-invariant Gate Distributions
Zhiyang Tan, Piet W. Brouwer
Random unitary circuits have become a model system to investigate information scrambling in quantum systems. In the literature, mostly random circuits with Haar-distributed gate op…
