Epitaxial patterning of nanometer-thick Y3Fe5O12 films with low magnetic damping
Shaozhen Li, Wei Zhang, Junjia Ding +3
Magnetic insulators such as yttrium iron garnet, Y3Fe5O12, with extremely low magnetic damping have opened the door for low power spin-orbitronics due to their low energy dissipati…
New pathways towards efficient metallic spin Hall spintronics
Matthias Benjamin Jungfleisch, Wei Zhang, Wanjun Jiang +1
Spin Hall effects interconvert spin- and charge currents due to spin-orbit interaction, which enables convenient electrical generation and detection of diffusive spin currents and…
Generation of magnetic skyrmion bubbles by inhomogeneous spin Hall currents
Olle Heinonen, Wanjun Jiang, Hamoud Somaily +2
Recent experiments have shown that magnetic skyrmion bubbles can be generated and injected at room temperature in thin films [W. Jiang et al, Science vol. 349, 283 (2015)]. Here, w…
Large spin-wave bullet in a ferrimagnetic insulator driven by spin Hall effect
M. B. Jungfleisch, W. Zhang, J. Sklenar +9
Due to its transverse nature, spin Hall effects (SHE) provide the possibility to excite and detect spin currents and magnetization dynamics even in magnetic insulators. Magnetic in…
Interface-driven spin-torque ferromagnetic resonance by Rashba coupling at the interface between non-magnetic materials
M. B. Jungfleisch, W. Zhang, J. Sklenar +4
The Rashba-Edelstein effect stems from the interaction between the electron's spin and its momentum induced by spin-orbit interaction at an interface or a surface. It was shown tha…
Driving and detecting ferromagnetic resonance in insulators with the spin Hall effect
Joseph Sklenar, Wei Zhang, Matthias B. Jungfleisch +6
We demonstrate the generation and detection of spin-torque ferromagnetic resonance in Pt/YIG bilayers. A unique attribute of this system is that the spin Hall effect lies at the he…
