Hideo Ohno,Daichi Chiba,Fumihiro Matsukura,T. Omiya,E. Abe,Tomasz Dietl,Tomasz Dietl,Yuzo Ohno,Keita Ohtani +8 more
TL;DR: By applying electric fields, the ability to externally control the properties of magnetic materials would be highly desirable from fundamental and technological viewpoints is demonstrated, particularly in view of recent developments in magnetoelectronics and spintronics.
Journal ArticleDOI
Quantum Hall Effect in Polar Oxide Heterostructures
Atsushi Tsukazaki,Akira Ohtomo,Akira Ohtomo,Tomohiro Kita,Yuzo Ohno,Hideo Ohno,Masashi Kawasaki +6 more
TL;DR: Demonstration of the quantum Hall effect in an oxide heterostructure presents the possibility of combining quantum Hall physics with the versatile functionality of metal oxides in complex heterostructures.
Journal ArticleDOI
Magnetic Tunnel Junctions for Spintronic Memories and Beyond
Shoji Ikeda,Jun Hayakawa,Young Min Lee,Fumihiro Matsukura,Yuzo Ohno,Takahiro Hanyu,Hideo Ohno +6 more
TL;DR: In this article, the authors reported that the magnetic tunnel magnetoresistance (TMR) ratio of the Co40Fe40B20 fixed and free layers made by sputtering with an industry-standard exchange bias structure and post deposition annealing at Ta = 400 degC.
Journal ArticleDOI
Spin Relaxation in GaAs(110) Quantum Wells
TL;DR: In this paper, the authors investigated electron spin relaxation time in (110) quantum wells (QWs), in which a predominant spin scattering mechanism [D'yakonov-Perel' (DP) mechanism] for conventional (100) QWs is substantially suppressed.
