Journal ArticleDOI
Tunable Backaction of a DC SQUID on an Integrated Micromechanical Resonator
Menno Poot,S. Etaki,Imran Mahboob,Koji Onomitsu,Hiroshi Yamaguchi,Ya. M. Blanter,H. S. J. van der Zant +6 more
TL;DR: The backaction of a dc superconducting quantum interference device (SQUID) position detector is measured on an integrated 1 MHz flexural resonator using the resistively and capacitively shunted junction model.
Journal ArticleDOI
Field-induced spin-state transition in the perovskite cobalt oxide Sr 1-x Y x CoO 3-δ
Shojiro Kimura,Y. Maeda,T. Kashiwagi,Hiroshi Yamaguchi,M. Hagiwara,Shin Yoshida,Ichiro Terasaki,K. Kindo +7 more
TL;DR: In this paper, the spin-state transition in perovskite Co oxide was observed in magnetic fields up to 53 T. The spin state transition is assisted by an internal field, originating from ferromagnetic exchange interaction between ions.
Journal ArticleDOI
High-sensitivity charge detection using antisymmetric vibration in coupled micromechanical oscillators
Hajime Okamoto,Norihito Kitajima,Koji Onomitsu,Reo Kometani,Shin'ichi Warisawa,Sunao Ishihara,Hiroshi Yamaguchi +6 more
TL;DR: In this paper, high sensitivity charge detection using antisymmetric vibration in two coupled GaAs oscillators is demonstrated, where the piezoelectric stress induced by a small gate-voltage modulation breaks the balance of the two oscillators, leading to the re-emergence of the ant-symmetric mode.
Journal ArticleDOI
Thickness-dependent electron accumulation in InAs thin films on GaAs ( 111 ) A : A scanning-tunneling-spectroscopy study
TL;DR: In this paper, the authors used tunneling spectroscopy to study quantum size effects on the electronic structure of thin InAs films grown on GaAs(111)A$ substrates, an example of a heterostructure with a relatively large lattice mismatch.
Journal ArticleDOI
NMR Spectroscopic Study of a DNA Duplex with Mercury-Mediated T-T Base Pairs
Yoshiyuki Tanaka,Hiroshi Yamaguchi,Shuji Oda,Yoshinori Kondo,Makoto Nomura,Chojiro Kojima,Akira Ono +6 more
TL;DR: The existence of mono-mercurated species is confirmed, because individual components gave independent NMR signals in the titration spectra.
