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…
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…
Crystal-field magnetostriction of the spin ice under ultrahigh magnetic fields
