Journal ArticleDOI
Magnetic control of ferroelectric polarization
Tsuyoshi Kimura,Tsuyoshi Kimura,Takeshi Goto,Hiroshi Shintani,Kyoko Ishizaka,Taka-hisa Arima,Yoshinori Tokura +6 more
TL;DR: The discovery of ferroelectricity in a perovskite manganite, TbMnO3, where the effect of spin frustration causes sinusoidal antiferromagnetic ordering and gigantic magnetoelectric and magnetocapacitance effects are found.
Journal ArticleDOI
Spin–Lattice Coupling in Ferroelectric Spiral Magnets: Comparison between the Cases of (Tb,Dy)MnO3 and CoCr2O4
Taka-hisa Arima,Yuichi Yamasaki,Takeshi Goto,Satoshi Iguchi,Kenya Ohgushi,Shigeki Miyasaka,Yoshinori Tokura +6 more
TL;DR: In this paper, the lattice modulation expected for various types of spiral magnetic ordering with a propagation vector Q m is discussed in terms of the symmetric (S i · S j type) and antisymmetric ( S i × S n type) expected for different types of magnetic ordering.

Laser beam machining method and device
Hiroshi Aoyama,Takeshi Goto,Mori Sadao,Hiroyuki Sugawara,Hideyuki Watanabe,後藤 健,森 貞雄,渡辺 英之,菅原 弘之,青山 博志 +9 more
TL;DR: In this paper, the amount of energy required for completing machining of a workpiece from its arbitrary machined state is preliminarily determined, collected in a data table and stored in a storage section.
Patent
Method and device for making hole
TL;DR: In this paper, the authors proposed a hole-making method in which a hole is formed in the vicinity of a positioning mark provided on the substrate, the positioning mark and the test hole are photographed by an imaging device, and the position of the substrate placed on the XY table is detected.
