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 cluster magnetic octupole domains in the antiferromagnetic Weyl semimetal Mn3Sn nanowire
Hironari Isshiki, Nico Budai, Ayuko Kobayashi +4
The antiferromagnetic Weyl semimetal Mn3Sn has attracted wide attention due to their vast anomalous transverse transport properties despite barely net magnetization. So far, the ma…
Crystal-field magnetostriction of the spin ice under ultrahigh magnetic fields
Nan Tang, Masaki Gen, Martin Rotter +9
We present a comprehensive study of the magnetoelastic properties of the Ising pyrochlore oxide HoTiO, known as spin ice, by means of high-field magnetostriction…
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…
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…
