Outline of Final Research Achievements

In order to realize wearable magnetoencephalography device for Brain Machine Interface usable in daily life, we have studied superferromagnetic phenomena of highly interacting magnetic fluids as a simple liquid magnetic shield for environmental noise. We have developed magnetic fluids containing magnetite nanoparticles with uniform size and shapes, and investigated spatial and magnetic correlation using small angle scattering technique. In addition, we have developed neutron transmission spectroscopy as a new technique for evaluating magnetic correlations.
