Large Voltage-Induced Changes in the Perpendicular Magnetic Anisotropy of an MgO-Based Tunnel Junction with an Ultrathin Fe Layer
Takayuki Nozaki,Anna Koziol-Rachwal,Anna Koziol-Rachwal,Witold Skowroński,Witold Skowroński,Vadym Zayets,Yoichi Shiota,Shingo Tamaru,Hitoshi Kubota,Akio Fukushima,Shinji Yuasa,Yoshishige Suzuki,Yoshishige Suzuki +12 more
TL;DR: In this paper, the authors studied VCMA in the fully epitaxial ultrathin Fe layer of a magnetic tunnel junction, and achieved an efficiency of almost 300 fJ V${}^{-1}$ m${}−1}
Journal ArticleDOI
Highly efficient voltage control of spin and enhanced interfacial perpendicular magnetic anisotropy in iridium-doped Fe/MgO magnetic tunnel junctions
Takayuki Nozaki,Anna Koziol-Rachwal,Anna Koziol-Rachwal,Masahito Tsujikawa,Yoichi Shiota,Xiandong Xu,Tadakatsu Ohkubo,Takuya Tsukahara,Shinji Miwa,Motohiro Suzuki,Shingo Tamaru,Hitoshi Kubota,Akio Fukushima,Kazuhiro Hono,Masafumi Shirai,Yoshishige Suzuki,Yoshishige Suzuki,Shinji Yuasa +17 more
TL;DR: In this article, an iridium-doped ultrathin iron film was used to improve the voltage-controlled magnetic anisotropy (VCMA) and the perpendicular magnetic aisotropic (PMA) properties of spintronic devices.
Journal ArticleDOI
Enhancement of perpendicular magnetic anisotropy and its electric field-induced change through interface engineering in Cr/Fe/MgO
Anna Koziol-Rachwal,Takayuki Nozaki,K. Freindl,Józef Korecki,Shinji Yuasa,Yoshishige Suzuki,Yoshishige Suzuki +6 more
TL;DR: In this paper, the authors shed light on the origin of large voltage-induced anisotropy change in Cr/Fe/MgO. They showed that PMA and its voltage control (VC) can be enhanced by controlled Cr doping at the Fe/mgO interface.

Enhancement of perpendicular magnetic anisotropy and its electric field-induced change through interface engineering in Cr/Fe/MgO
Anna Koziol-Rachwal,Takayuki Nozaki,K. Freindl,Józef Korecki,Shinji Yuasa,Yoshishige Suzuki,Yoshishige Suzuki +6 more
TL;DR: It is shown that PMA and its VC can be enhanced by controlled Cr doping at the Fe/MgO interface, and a maximum value of the voltage-controlled magnetic anisotropy (VCMA) effect was demonstrated due to Cr insertion.
Journal ArticleDOI
Giant in-plane magnetic anisotropy in epitaxial bcc Co/Fe(110) bilayers
M. Ślęzak,M. Ślęzak,T. Ślęzak,K. Matlak,B. Matlak,P. Dróżdż,Tomasz Giela,D. Wilgocka-Ślęzak,N. Pilet,Jörg Raabe,Anna Koziol-Rachwal,Anna Koziol-Rachwal,Józef Korecki +12 more
TL;DR: In this paper, in-plane magnetic surface anisotropy in epitaxial bcc Co/Fe bilayers on W(110) bilayers was investigated and it was shown that a small fraction of a Co monolayer can reorient the magnetization of the bulk-like Fe film.
