Determination of the Dzyaloshinskii-Moriya interaction using pattern recognition and machine learning
Masashi Kawaguchi, Kenji Tanabe, Keisuke Yamada +4
Machine learning is applied to a large number of modern devices that are essential in building energy efficient smart society. Audio and face recognition are among the most well-kn…
Domain wall resistance in CoFeB-based heterostructures with interface Dzyaloshinskii-Moriya interaction
Yuto Ishikuro, Masashi Kawaguchi, Yong-Chang Lau +2
We have studied the domain wall resistance in W/Ta/CoFeB/MgO heterostructures. The Ta layer thickness is varied to control the type of domain walls via changes in the interfacial D…
Current-induced modulation of interfacial Dzyaloshinskii-Moriya interaction
Naoaki Kato, Masashi Kawaguchi, Yong-Chang Lau +3
The Dzyaloshinskii-Moriya (DM) interaction is an antisymmetric exchange interaction that is responsible for the emergence of chiral magnetism. The origin of the DM interaction, how…
Direct current voltage induced by microwave signal in a ferromagnetic wire
A. Yamaguchi, K. Motoi, H. Miyajima +1
Experimental results of rectification of a constant wave radio frequency (RF) current flowing in a single-layered ferromagnetic wire are presented. We show that a detailed external…
Threshold Current of Domain Wall Motion under Extrinsic Pinning, -Term and Non-Adiabaticity
Gen Tatara, Toshihiko Takayama, Hiroshi Kohno +3
Threshold current of domain wall motion under spin-polarized electric current in ferromagnets is theoretically studied based on the equation of motion of a wall in terms of collect…
Current-induced Vortex Motion by Spin-Transfer Torque
Junya Shibata, Yoshinobu Nakatani, Gen Tatara +2
We investigate the dynamics of a magnetic vortex driven by spin-transfer torque due to spin current in the adiabatic case. The vortex core represented by collective coordinate expe…
