Electric Current Control of Helimagnetic Chirality from a Multidomain State in the Helimagnet MnAu
Yuta Kimoto, Hidetoshi Masuda, Jun-ichiro Ohe +3
In this paper, we study the domain wall dynamics under electric current in the helimagnet MnAu. We have found that the threshold electric current of the transition from a multi…
Direct demonstration of electric chirality control in a helimagnetic YMnSn by spin-polarized neutron scattering
Hidetoshi Masuda, Yutaro Yanagisawa, Kazuki Ohishi +3
The spiral handedness of magnetic moments, referred to as chirality, gives rise to emergent electromagnetic phenomena in helimagnets. In insulating helimagnets, known as multiferro…
Current-induced sliding motion in a helimagnet MnAu
Yuta Kimoto, Hidetoshi Masuda, Takeshi Seki +4
We found signatures of current-induced sliding motion in helimagnetic thin films. An abrupt change in differential resistivity occurred at a threshold bi…
Magnetic excitations in the noncentrosymmetric magnet Sr2MnSi2O7
Masahiro Kawamata, Xiaoqi Pang, Hiroshi Murakawa +7
Magnetic excitations in the noncentrosymmetric magnet SrMnSiO were investigated through inelastic neutron scattering measurements. Major magnetic excitations are limite…
Magnetic structure of the noncentrosymmetric magnet Sr2MnSi2O7 through irreducible representation and magnetic space group analyses
Y. Nambu, M. Kawamata, X. Pang +6
Magnetic structures of the noncentrosymmetric magnet SrMnSiO were examined through neutron diffraction for powder and single-crystalline samples, as well as magnetometr…
