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…
Electrical detection of antiferromagnetic dynamics in Gd-Co thin films by using a 154-GHz gyrotron irradiation
S. Funada, Y. Ishikawa, M. Kimata +8
THz magnetization dynamics is a key property of antiferromagnets as well as ferrimagnets that could harness the THz forefront and spintronics. While most of the present THz measure…
Temperature dependence of magnetic resonance in ferrimagnetic GdFeCo alloys
Takaya Okuno, Se Kwon Kim, Takahiro Moriyama +10
We provide a macroscopic theory and experimental results for magnetic resonances of antiferromagnetically-coupled ferrimagnets. Our theory, which interpolates the dynamics of antif…
Spin wave propagation in ferrimagnetic
Shinsaku Funada, Tomoe Nishimura, Yoichi Shiota +4
Recent advances in antiferromagnetic spin dynamics using rare-earth (RE) and transition-metal (TM) ferrimagnets have attracted much interest for spintronic devices with a high spee…
Spin-transfer torques for domain walls in antiferromagnetically coupled ferrimagnets
Takaya Okuno, Duck-Ho Kim, Se-Hyeok Oh +13
Antiferromagnetic materials are outstanding candidates for next generation spintronic applications, because their ultrafast spin dynamics makes it possible to realize several order…
Enhanced perpendicular magnetocrystalline anisotropy energy in an artificial magnetic material with bulk spin-momentum coupling
Abdul-Muizz Pradipto, Kay Yakushiji, Woo Seung Ham +8
We systematically investigate the perpendicular magnetocrystalline anisotropy (MCA) in CoPt/Pd-based multilayers. Our magnetic measurement data shows that the asymmetric Co/Pd/P…
Low magnetic damping of ferrimagnetic GdFeCo alloys
Duck-Ho Kim, Takaya Okuno, Se Kwon Kim +12
We investigate the Gilbert damping parameter for rare earth (RE)-transition metal (TM) ferrimagnets over a wide temperature range. Extracted from the field-driven magnetic domain-w…
Correlation between Magnetic Properties and Depinning Field in Field-Driven Domain Wall Dynamics in GdFeCo Ferrimagnets
Tomoe Nishimura, Duck-Ho Kim, Yuushou Hirata +7
The influence of temperature on the magnetic-field-driven domain wall (DW) motion is investigated in GdFeCo ferrimagnets with perpendicular magnetic anisotropy (PMA). We find that…
Voltage-assisted Magnetization Switching in Ultrathin Fe80Co20 Alloy Layers
Yoichi Shiota, Takuto Maruyama, Takayuki Nozaki +3
Growing demands for the voltage-driven spintronic applications with ultralow-power consumption have led to new interest in exploring the voltage-induced magnetization switching in…
