Chirality-dependent spin current generation in a helimagnet: zero-field probe of chirality
Hidetoshi Masuda, Takeshi Seki, Jun-ichiro Ohe +3
In a magnetic texture, the spin of a conduction electron is forced to be aligned to the localized moment. As a result, the topology of the magnetic texture affects the electron dyn…
Microwave impedance microscopy imaging of acoustic topological edge mode on a patterned substrate
Yoichi Nii, Yoshinori Onose
We have studied acoustic topological edge modes in a honeycomb phononic crystal composed of metallic nano-pillars on a LiNbO substrate. Acoustic band calculations show that the…
Room-temperature chirality switching in a helimagnetic thin film
Hidetoshi Masuda, Takeshi Seki, Yoichi Nii +3
Helimagnetic structures, in which the magnetic moments are spirally ordered, host an internal degree of freedom called chirality (or helicity) corresponding to the handedness of th…
Elastic study of electric quadrupolar correlation in the paramagnetic state of a frustrated quantum magnet
Y. Nii, Y. Hirokane, S. Nakamura +4
Electric quadrupolar state in a frustrated quantum magnet has been studied by means of ultrasonic and magnetostriction measurements. A single crys…
Chirality memory stored in magnetic domain walls in the ferromagnetic state of MnP
N. Jiang, Y. Nii, H. Arisawa +2
Chirality in a helimagnetic structure is determined by the sense of magnetic moment rotation. We found that the chiral information did not disappear even after the phase transition…
Magnetization control by angular momentum transfer from surface acoustic wave to ferromagnetic spin moments
R. Sasaki, Y. Nii, Y. Onose
The angular momentum interconversion between electron spin and other type of angular momenta is useful to develop new spintronic functionalities. The conversions from the angular m…
