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…
Universal -suppression of magnonic shot noise in diffusive insulating magnets
Kouki Nakata, Yuichi Ohnuma, Mamoru Matsuo
Extending a Boltzmann-Langevin theory to magnons, we show a universality of current-noise suppression in diffusive systems against the difference of quantum-statistical properties…
Asymmetric quantum shot noise in magnon transport
Kouki Nakata, Yuichi Ohnuma, Mamoru Matsuo
We study a frequency-dependent noise-to-current ratio for asymmetric, symmetric, and noncommutative current-noise in a ferromagnetic insulating junction, and extract quantum-mechan…
Spin transport in half-metallic ferromagnets
Y. Ohnuma, M. Matsuo, S. Maekawa
We theoretically investigate spin transport in half-metallic ferromagnets at finite temperatures. The side-jump and skew-scattering contributions to spin Hall conductivity are deri…
Enhanced DC Spin Pumping into a Fluctuating Ferromagnet near Tc
Yuichi Ohnuma, Hiroto Adachi, Eiji Saitoh +1
A linear-response formulation of the dc spin pumping, i.e., a spin injection from a precessing ferromagnet into an adjacent spin sink, is developed in view of describing many-body…
