A magnetic field is predicted to emerge on a particle in a rotating body even if the body is electrically neutral. This emergent field is called a Barnett field. We show that nuclear magnetic resonance (NMR) enables direct measurement of the Barnett field in solids. We rotated both a sample and an NMR coil synchronously at high speed and found an NMR shift whose sing reflects that of the nuclear magnetic moments. This result provides direct evidence of the Barnett field. The use of NMR for Barnett field measurement enables the unknown signs of nuclear magnetic moments in solids to be determined.

Ultracentrifuge experiment on AgI super-ionic conductor

Ono, Masao; Okayasu, Satoru; Iguchi, Yusuke*; Esaka, Fumitaka; Bagum, R.*; Haruki, Rie; Mashimo, Tsutomu*

We had realized the composition gradient of elements or isotopes in some binary alloys or single element by solid-state centrifugation. While, it might difficult to realize graded structure of elements in binary ionic crystal by centrifugation as it strongly keeps their stoichiometry. However, isotope fractionation in binary ionic crystal by centrifugation might be expected as the self-diffusion of ions occurs. We have planed the ultracentrifuge experiments on $$alpha$$-AgI superionic conductor to investigate the isotope effect in binary ionic crystal under a strong centrifugal acceleration field. $$alpha$$-AgI superionic conductor is suitable for the confirmation experiment as it is an intrinsic ionic crystal and Ag ions have high diffusivity. For the first stage, we have experimentally searched the experimental conditions of magnitude of centrifugal acceleration and temperature that ensure the experiment without decomposition. It is confirmed that the combination of experimental conditions of up to 6.1$$times$$10$$^{5}$$ g, 350$$^{circ}$$C, 24h ensure the experiment without decomposition at least.

We present spin pumping using a Heusler alloy Co$$_2$$MnSi/Pt bilayer film. A spin current is produced by a ferromagnetic resonance (FMR) technique. The pure spin current injected into the Pt layer from the Co$$_2$$MnSi layer is detected by the inverse spin-Hall effect (ISHE), which converts the spin current into an electric current. We estimated a damping constant of the Co$$_2$$MnSi/Pt bilayer film from an angular dependence of FMR spectra. Using the damping constant efficiency of spin pumping from the Co$$_2$$MnSi layer is evaluated. We found that a mixing conductance at the Co$$_2$$MnSi/Pt interface is comparable to that at a permalloy/Pt interface.

Isotope distribution in pure indium after liquid-state centrifugation

Ono, Masao; Okayasu, Satoru; Esaka, Fumitaka; Haruki, Rie; Mashimo, Tsutomu*

Journal of the Japan Society of Microgravity Application, 28(2), p.S89 - S91, 2011/04

An ultracentrifuge experiment was performed on a pure liquid-indium at acceleration field of 8.2$$times$$10$$^{5}$$ g at 300$$^{circ}$$C for 100 hours. The isotope ratio measurements were performed on the centrifuged specimen with Secondary Ion Mass Spectrometer (CAMECA IMS-6f). $$^{113}$$In/$$^{115}$$In isotope ratio on the specimen changed with negative gradient in the direction of centrifugal force approximately 1.3%. The measurement result indicated that the heavy $$^{115}$$In isotopes moved in the direction of the centrifugal force and the light $$^{113}$$In isotopes moved in the counter direction in the specimen. At the session, we will present both the result and an approach to find a precondition to develop an isotope separation process using the phenomenon.
