Giant effective damping of octupole oscillation in an antiferromagnetic Weyl semimetal
Shinji Miwa, Satoshi Iihama, Takuya Nomoto +8
A magnetic Weyl semimetal is a recent focus of extensive research as it may exhibit large and robust transport phenomena associated with topologically protected Weyl points in mome…
Parity-controlled spin-wave excitations in synthetic antiferromagnets
A. Sud, Y. Koike, S. Iihama +3
We report in this study the current-induced-torque excitation of acoustic and optical modes in Ta/NiFe/Ru/NiFe/Ta synthetic antiferromagnet stacks grown on SiO2/Si substrates. The…
Spin injection characteristics of Py/graphene/Pt by gigahertz and terahertz magnetization dynamics driven by femtosecond laser pulse
H. Idzuchi, S. Iihama, M. Shimura +3
Spin transport characteristics of graphene has been extensively studied so far. The spin transport along c-axis is however reported by rather limited number of papers. We have stud…
Interface-induced field-like optical spin torque in a ferromagnet/heavy metal heterostructure
Satoshi Iihama, Kazuaki Ishibashi, Shigemi Mizukami
The manipulation of magnetization in a metallic ferromagnet by using optical helicity has been much attracted attention for future opto-spintronic devices. The optical helicity ind…
Tunable magnon-magnon coupling in synthetic antiferromagnets
A. Sud, C. W. Zollitsch, A. Kamimaki +5
In this work, we study magnon-magnon coupling in synthetic antiferromagnets (SyAFs) using microwave spectroscopy at room temperature. Two distinct spin-wave modes are clearly obser…
Large Spin Anomalous Hall Effect in L1-FePt: Symmetry and Magnetization Switching
Takeshi Seki, Satoshi Iihama, Tomohiro Taniguchi +1
We quantitatively evaluate a spin anomalous Hall effect (SAHE), generating spin angular momentum flow (spin current, ), in an L1-FePt ferromagnet by exploiting…
