Research activity:
I developed a Raman-scattering measurement system in magnetic field up to 12 T.
Using this system, I measure Raman scattering in Mn oxides and spin-Peierls systems.
I also calculate magnetic specific heat in a quantum spin system
to compare with that measured by quasi-elastic scattering of lights.
I also provide the data of magnetic susceptibility
in a spin-gap system to other experimentalists.
Educational activity:
I developed many kinds of educational tools for university students,
such as digital circuit learning tool,
Hall-effects measurement system,
and specific-heat measurement system.
(Subject of research)
Research in magnetism obtained from the magnetic light scattering from spin multiplets
Optical properties of Mn oxides under multi-extreme conditions
Raman spectra in magnon BEC state
Optical Properties in Spin-Gap Systems under multiextreme condition
Optical Properties in Manganites

Nano Hybrids and Composites, 40 7-12, Jul 31, 2023 Peer-reviewedLast authorPreparation conditions of titanium oxide (TiO2) powders were examined by the hydrolysis of titanium potassium oxalate (K2TiO(C2O4)2), through the homogeneous precipitation method (80oC for 24 h) and hydrothermal treatment (160 or 170oC for 1 h). According to the Rietveld analysis, almost a single phase of anatase TiO2 could be obtained by the hydrothermal treatment at 160oC for 1 h, followed by the heating at 900oC for 10 min in air. The molar ratio of anatase to rutile TiO2 was found to be controlled by optimizing the hydrothermal conditions in the solution and the heating conditions in air for the photocatalytic activity.

e-Journal of Surface Science and Nanotechnology, 10(2012) 321-324, Jul 7, 2012 Peer-reviewedWe study micro-Raman spectroscopy in free-standing single GaN nanocolumns with 0.45-2.1 μm diameters, which are synthesized by rf-plasma-assisted molecular beam epitaxy. We clearly observe the breakdown of the polarization selection rule of Raman spectra from E2H phonon, when the diameter of nanocolumn is thinner than four times the wavelength of incident light inside the sample. The selection rule gets recovered with increasing diameter of nanocolumn. Moreover, we observe quasi-TO phonon modes, which strongly affects the Raman spectra from the A1(TO) and E1(TO) phonons.
