Journal ArticleDOI
Atomic disorder effects on half-metallicity of the full-Heusler alloys Co 2 ( Cr 1 − x Fe x ) Al : A first-principles study
TL;DR: In this paper, the authors investigated the atomic disorder effects on the half-metallicity of the full-Heusler alloy and showed that disorder between Cr and Al does not significantly reduce the spin polarization of the parent alloy.
Journal ArticleDOI
Low damping constant for Co2FeAl Heusler alloy films and its correlation with density of states
Shigemi Mizukami,D. Watanabe,Mikihiko Oogane,Yasuo Ando,Yoshio Miura,Masafumi Shirai,Terunobu Miyazaki +6 more
TL;DR: Gilbert damping for epitaxial Co2FeAl Heusler alloy films was investigated by analyzing the data of ferromagnetic resonance measured at the frequency of 2.20 GHz as discussed by the authors.
Journal ArticleDOI
Role of Electronic Structure in the Martensitic Phase Transition of Ni_2Mn_ Sn_ Studied by Hard-X-Ray Photoelectron Spectroscopy and Ab Initio Calculation
Mao Ye,Akio Kimura,Yoshio Miura,Masafumi Shirai,Yi-Tao Cui,Kenya Shimada,Hirofumi Namatame,Masaki Taniguchi,Masaki Taniguchi,Shigenori Ueda,Keisuke Kobayashi,Ryosuke Kainuma,Toetsu Shishido,K. Fukushima,Takeshi Kanomata +14 more
TL;DR: The underlying mechanism of the martensitic phase transition (MPT) in a new class of ferromagnetic shape memory alloys, Ni2Mn1+xSn1-x, is revealed by the combination of bulk-sensitive hard-x-ray photoelectron spectroscopy and a first-principles density-functional calculation.
Journal ArticleDOI
Mechanism of large magnetoresistance in Co 2 MnSi / Ag / Co 2 MnSi devices with current perpendicular to the plane
Yuya Sakuraba,K. Izumi,T. Iwase,S. Bosu,Kyosuke Saito,Koki Takanashi,Yoshio Miura,K. Futatsukawa,Kazutaka Abe,Masafumi Shirai +9 more
TL;DR: In this article, a fully epitaxial current-perpendicular-to-plane giant magnetoresistance (MR) device with half-metallic electrodes and a spacer was fabricated to investigate the relationship between the chemical ordering in CMS and its MR properties, including bulk and interface spin-asymmetry coefficients.
Journal ArticleDOI
Extensive study of giant magnetoresistance properties in half-metallic Co2(Fe,Mn)Si-based devices
Yuya Sakuraba,M. Ueda,Yoshio Miura,Kazuhisa Sato,S. Bosu,Kyosuke Saito,Masafumi Shirai,T. J. Konno,Koki Takanashi +8 more
TL;DR: In this article, a fully epitaxial Co2FexMn1−xSi(CFMS)/Ag/Co2FExMn 1−x Si current-perpendicular-to-plane giant magnetoresistive devices with various Fe/Mn ratios x and top CFMS layer thicknesses tCFMS were prepared.
