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…
Observation of chiral domain walls in an octupole-ordered antiferromagnet
Moeta Tsukamoto, Zhewen Xu, Tomoya Higo +10
Spin chirality in antiferromagnets offers new opportunities for spintronics. The kagome antiferromagnet Mn3Sn is a paradigmatic material in which the antiferromagnetic order parame…
Exfoliation and Optical Properties of S=1 Triangular Lattice Antiferromagnet NiGaS
Jazzmin Victorin, Aleksandar Razpopov, Tomoya Higo +5
Two-dimensional (2D) van der Waals (vdW) materials have been an exciting area of research ever since scientists first isolated a single layer of graphene. Single layer magnetic mat…
