Coexistence of Magnon-Induced Optical Vortex and Gaussian Beam Scattering Assisted by Rotational Umklapp Process

Ryusuke Hisatomi, Kotaro Taga, Hisakazu Matsuki +3

The exploitation of crystal-lattice symmetries to engineer angular momentum transfer between structured light and magnons marks a novel frontier for optomagnonic research. In Brill…

All-optical magnetization reversal via x-ray magnetic circular dichroism

Kihiro T. Yamada, Akira Izumi, Tetsuya Ikebuchi +15

Light polarization is one of the most fundamental features, equivalent to energy and coherence. Magnetism changes light polarization, and vice versa. The irradiation of intense cir…

Néel vector rotation driven by spin-orbit torque in amorphous ferrimagnetic GdCo

Tetsuma Mandokoro, Yoichi Shiota, Tomoya Ito +5

Spin superfluidity, a phenomenon enabling low dissipative spin transport analogous to superfluidity in liquid helium and superconductivity in electronic systems, has remained a the…

Handedness manipulation of propagating antiferromagnetic magnons

Yoichi Shiota, Tomohiro Taniguchi, Daiju Hayashi +5

Antiferromagnetic magnons possess a distinctive feature absent in their ferromagnetic counterparts: the presence of two distinct handedness modes, the right-handed (RH) and left-ha…
