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…
Ultrafast electron heating as the dominant driving force of photoinduced terahertz spin currents
Reza Rouzegar, Pilar Jimenez-Cavero, Oliver Gueckstock +9
Ultrafast spintronics strongly relies on the generation, transport, manipulation and detection of terahertz spin currents (TSCs). In F|HM stacks consisting of a ferromagnetic layer…
Momentum-Resolved Fingerprint of Mottness in Layer-Dimerized NbBr
Mihir Date, Francesco Petocchi, Yun Yen +20
In a well-ordered crystalline solid, insulating behaviour can arise from two mechanisms: electrons can either scatter off a periodic potential, thus forming band gaps that can lead…
Switching of magnetic domains in a noncollinear antiferromagnet at the nanoscale
Atul Pandey, Prajwal Rigvedi, Edouard Lesne +8
Antiferromagnets that display very small stray magnetic field are ideal for spintronic applications. Of particular interest are non-collinear, chiral antiferromagnets of the type M…
Integration and characterization of micron-sized YIG structures with very low Gilbert damping on arbitrary substrates
P. Trempler, R. Dreyer, P. Geyer +3
We present a novel process that allows the transfer of monocrystalline yttrium-iron-garnet microstructures onto virtually any kind of substrate. The process is based on a recently…
Monocrystalline free standing 3D yttrium iron garnet magnon nano resonators
F. Heyroth, C. Hauser, P. Trempler +6
Nano resonators in which mechanical vibrations and spin waves can be coupled are an intriguing concept that can be used in quantum information processing to transfer information be…
