Spin-wave propagation in cubic anisotropic materials
Koji Sekiguchi, Seo-Won Lee, Hiroaki Sukegawa +4
The information carrier of modern technologies is the electron charge whose transport inevitably generates Joule heating. Spin-waves, the collective precessional motion of electron…
Sub-Poissonian shot noise in CoFeB/MgO/CoFeB-based magnetic tunneling junctions
Tomonori Arakawa, Koji Sekiguchi, Shuji Nakamura +7
We measured the shot noise in the CoFeB/MgO/CoFeB-based magnetic tunneling junctions with a high tunneling magnetoresistance ratio (over 200% at 3 K). Although the Fano factor in t…
Evolution of the Kondo Effect in a Quantum Dot Probed by the Shot Noise
Yoshiaki Yamauchi, Koji Sekiguchi, Kensaku Chida +6
We measure the current and shot noise in a quantum dot (QD) in the Kondo regime to address the non-equilibrium properties of the Kondo effect. By systematically tuning the temperat…
