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…
