Large Photoelasticity in Topological Antiferromagnet MnSn Studied by Coherent Acoustic Phonon
Yuchen Wang, Takuya Matsuda, Yuta Murotani +5
We investigate the role of ultrafast strain on the electronic and optical responses in topological antiferromagnet MnSn thin films using near-infrared femtosecond pump-probe sp…
Crossover between intrinsic and temperature-assisted regimes in spin-orbit torque switching of antiferromagnetic order
Takumi Matsuo, Tomoya Higo, Daisuke Nishio-Hamane +7
Intensive studies have been made on antiferromagnets as candidate materials for next generation memory bits due to their ultrafast dynamics reaching picosecond time scales. Recent…
Emergence of high-mobility carriers in topological kagome bad metal MnSn by intense photoexcitation
Takuya Matsuda, Tomoya Higo, Kenta Kuroda +13
Kagome-lattice materials offer novel playgrounds of exploring topologically nontrivial states of electrons under influence of many-body interactions. A noncollinear kagome antiferr…
Ultrafast Dynamics of Intrinsic Anomalous Hall Effect in the Topological Antiferromagnet Mn3Sn
Takuya Matsuda, Tomoya Higo, Takashi Koretsune +8
We investigate ultrafast dynamics of the anomalous Hall effect (AHE) in the topological antiferromagnet Mn3Sn with sub-100 fs time resolution. Optical pulse excitations largely ele…
