High-Field Terahertz Spin Resonance in CrO above the Spin-Flop Transition
Kaiyang Huang, Yuto Kinoshita, Natsuki Kanda +4
We report single-shot terahertz time-domain spectroscopy of CrO in pulsed magnetic fields up to 30 T. Well above the spin-flop field, in the 20-30 T range, the resonance fr…
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…
Anomalous Hall transport by optically injected isospin degree of freedom in Dirac semimetal thin film
Yuta Murotani, Natsuki Kanda, Tomohiro Fujimoto +7
Chirality of massless fermions emergent in condensed matter is a key to understand their characteristic behavior as well as to exploit their functionality. However, chiral nature o…
Semiconducting Electronic Structure of the Ferromagnetic Spinel Revealed by Soft-X-Ray Angle-Resolved Photoemission Spectroscopy
Hiroaki Tanaka, Andrei V. Telegin, Yurii P. Sukhorukov +12
We study the electronic structure of the ferromagnetic spinel by soft-x-ray angle-resolved photoemission spectroscopy (SX-ARPES) and first-p…
Disentangling the Competing Mechanisms of Light-Induced Anomalous Hall Conductivity in Three-Dimensional Dirac Semimetal
Yuta Murotani, Natsuki Kanda, Tomohiro Fujimoto +7
We experimentally elucidate the origin of the anomalous Hall conductivity in a three-dimensional Dirac semimetal, CdAs, driven by circularly polarized light. Using time-res…
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…
Stimulated Rayleigh Scattering Enhanced by a Longitudinal Plasma Mode in a Periodically Driven Dirac Semimetal CdAs
Yuta Murotani, Natsuki Kanda, Tatsuhiko N. Ikeda +6
Using broadband (12-45 THz) multi-terahertz spectroscopy, we show that stimulated Rayleigh scattering dominates the transient optical conductivity of cadmium arsenide, a Dirac semi…
X-ray spectroscopic study of BaFeO thin films; an Fe ferromagnetic insulator
T. Tsuyama, T. Matsuda, S. Chakraverty +7
We investigated the electronic and magnetic properties of fully oxidized BaFeO3 thin films, which show ferromagnetic-insulating properties with cubic crystal structure, by hard x-r…
