Journal ArticleDOI
Transmission of electrical signals by spin-wave interconversion in a magnetic insulator
Y. Kajiwara,Kazuya Harii,Saburo Takahashi,Jun-ichiro Ohe,Ken-ichi Uchida,Masaki Mizuguchi,H. Umezawa,H. Kawai,Kazuya Ando,Kazuya Ando,Koki Takanashi,Sadamichi Maekawa,Eiji Saitoh,Eiji Saitoh,Eiji Saitoh +14 more
TL;DR: It is shown that a spin wave in an insulator can be generated and detected using spin-Hall effects, which enable the direct conversion of an electric signal into aspin wave, and its subsequent transmission through (and recovery from) an insulators over macroscopic distances.
Journal ArticleDOI
Large voltage-induced magnetic anisotropy change in a few atomic layers of iron
Takuto Maruyama,Yoichi Shiota,Takayuki Nozaki,K. Ohta,N. Toda,Masaki Mizuguchi,Masaki Mizuguchi,Ashwin Tulapurkar,Teruya Shinjo,Masashi Shiraishi,Shigemi Mizukami,Yasuo Ando,Yoshishige Suzuki +12 more
TL;DR: Simulations confirm that voltage-controlled magnetization switching in magnetic tunnel junctions is possible using the anisotropy change demonstrated here, which could be of use in the development of low-power logic devices and non-volatile memory cells.
Journal ArticleDOI
Anomalous Nernst Effect in L10-FePt/MnGa Thermopiles for New Thermoelectric Applications
Yuya Sakuraba,Kota Hasegawa,Masaki Mizuguchi,Masaki Mizuguchi,Takahide Kubota,Shigemi Mizukami,Terunobu Miyazaki,Koki Takanashi +7 more
TL;DR: In this paper, a new type of thermopile consisting of two ferromagnetic materials with anomalous Nernst effects (ANEs) of opposite signs was proposed, where the combination of perpendicularly magnetized FePt and MnGa wires enhances the ANE voltage effectively.
Journal ArticleDOI
Fabrication, magnetic properties, and electronic structures of nanoscale zinc-blende MnAs dots (invited)
TL;DR: In this article, the zinc-blende MnAs dots were successfully fabricated on a sulfur-passivated GaAs (001) surface by molecular-beam epitaxy and the crystalline structure was not the same as that of bulk MnAs with NiAs-type hexagonal structure, but of zincblende type.
Journal ArticleDOI
Energy-harvesting materials based on the anomalous Nernst effect
TL;DR: This review discusses various topics related to the methods to modulate the ANE for its thermoelectric applications and reviews strategies to design materials to obtain large ANE including Weyl magnets and thermoeLECTric devices for effectively utilizing the ANe.
