Nuclear-spin evidence of insulating and antiferromagnetic state of CuO2 planes in superconducting Pr2Ba4Cu7O15-δ

S. Nishioka, S. Sasaki, S. Nakagawa +4

In contrast to the "Pr-issue" that neither PrBa2Cu3O7 (Pr123) nor PrBa2Cu4O8 (Pr124) shows superconductivity (SC), we have observed 100%-fraction of SC in an oxygen-reduced Pr2Ba4C…

1/f^2 spectra of decoherence noise on ^75^As nuclear spins in bulk GaAs

Susumu Sasaki, Takanori Miura, Kohsuke Ikeda +5

To identify the decoherence origin, frequency spectra using multiple π-pulses have been extensively studied. However, little has been discussed on how to define the spectral intens…

Measurement of the Noise Spectrum Using a Multiple-Pulse Sequence

Tatsuro Yuge, Susumu Sasaki, Yoshiro Hirayama

A method is proposed for obtaining the spectrum for noise that causes the phase decoherence of a qubit directly from experimentally available data. The method is based on a simple…

Direct Observation of Local Magnetic Field Generated by Micromagnet

Shinji Watanabe, Susumu Sasaki, Shinya Sato +2

Using standard nuclear magnetic resonance (NMR) technique and a well-fabricated sample, we have succeeded in directly observing local magnetic field generated by a micro-magnet Ni4…

29Si Nuclear-Spin Decoherence Process Directly Observed by Multiple Spin-Echoes for Pure and Carrier-less Silicon

Shinji Watanabe, Susumu Sasaki

We report on the 29Si nuclear spin decoherence time at room temperature for a pure (99.99999%, 7N) and carrier-less (p-type, doping level of 10^15cm-3) silicon in which 29Si nuclei…
