Magnon Current Generation by Dynamical Distortion
Junji Fujimoto, Mamoru Matsuo
The interaction between spin and nanomechanical degrees of freedom attracts interest from the viewpoint of basic science and device applications. We study the magnon current induce…
Enhancement of domain-wall mobility detected by NMR at the angular momentum compensation temperature
Masaki Imai, Hiroyuki Chudo, Mamoru Matsuo +2
The angular momentum compensation temperature of ferrimagnets has attracted much attention because of high-speed magnetic dynamics near . We show that NMR ca…
Determination of spin relaxation time and spin diffusion length by oscillation of spin pumping signal
Junji Fujimoto, Mamoru Matsuo
We theoretically investigate a manipulation method of nonequilibrium spin accumulation in the paramagnetic normal metal of a spin pumping system, by using the spin precession motio…
Angular momentum compensation manipulation to room temperature of the ferrimagnet HoDyFeO detected by the Barnett effect
Masaki Imai, Hiroyuki Chudo, Masao Ono +5
We demonstrate that the angular momentum compensation temperature , at which the net angular momentum in the sample disappears, can be controlled in HoFeO by pa…
Dirac-Surface-State Modulated Spin Dynamics in a Ferrimagnetic Insulator at Room Temperature
Chi Tang, Qi Song, Cui-Zu Chang +10
This work demonstrates dramatically modified spin dynamics of magnetic insulator (MI) by the spin-momentum locked Dirac surface states of the adjacent topological insulator (TI) wh…
Observation of gyromagnetic reversal
Masaki Imai, Yudai Ogata, Hiroyuki Chudo +6
We report direct observation of gyromagnetic reversal, which is the sign change of gyromagnetic ratio in a ferrimagnet HoFeO, by using the Barnett effect measurement…
