Excitation and relaxation dynamics of spin-waves triggered by ultrafast photo-induced demagnetization in a ferrimagnetic insulator
Yusuke Hashimoto, Koji Sato, Tom H. Johansen +1
Excitation and propagation dynamics of spin waves in an iron-based garnet film under out-of-plane magnetic field were investigated by time-resolved magneto-optical imaging. The exp…
Skyrmion Hall Effect Revealed by Direct Time-Resolved X-Ray Microscopy
Kai Litzius, Ivan Lemesh, Benjamin Krüger +14
Magnetic skyrmions are highly promising candidates for future spintronic applications such as skyrmion racetrack memories and logic devices. They exhibit exotic and complex dynamic…
Anomalous Hall effect driven by dipolar spin waves in uniform ferromagnets
Kei Yamamoto, Koji Sato, Eiji Saitoh +1
A new type of anomalous Hall effect is shown to arise from the interaction of conduction electrons with dipolar spin waves in ferromagnets. This effect exists even in homogeneous f…
