Kohei Hamaya,M. Kitabatake,Kenji Shibata,Minkyung Jung,Minoru Kawamura,Kazuhiko Hirakawa,Tomoki Machida,S. Ishida,Y. Arakawa +8 more
TL;DR: In this paper, an electric field control of tunneling magnetoresistance (TMR) effect in a semiconductor quantum-dot (QD) spin-valve device was demonstrated.
Journal ArticleDOI
Kondo effect in a semiconductor quantum dot coupled to ferromagnetic electrodes
Kohei Hamaya,M. Kitabatake,Kenji Shibata,Minkyung Jung,Minoru Kawamura,Kazuhiko Hirakawa,Tomoki Machida,Tomoyasu Taniyama,S. Ishida,Yasuhiko Arakawa +9 more
TL;DR: In this paper, the Kondo resonance at N = 3 splits clearly without external magnetic fields, and then the splitting is gradually reduced with applying magnetic fields (B), and the kondo effect is almost restored at B = 1.2T.
