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…
Symmetry and Nonstoichiometry as Possible Origin of Ferromagnetism in Nanoscale oxides
Takashi Uchino, Toshinobu Yoko
We show through density functional theory calculations that extended magnetic states can inherently occur in oxides as the size of the crystals is reduced down to the nanometer sca…
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…
