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

Journal of Physics: Conference Series, 3161(1) 012033-012033, Jan 1, 2026Abstract We investigate the effects of Fe and Sr doping on the magnetoelectric properties of CaBaCo 4 O 7 , a multiferroic polar magnet. Substituting Fe at Co sites extends the temperature and field ranges of magnetoelectric responses, transforming the material from pyroelectric to ferroelectric. Similarly, Sr doping at Ca sites induces structural changes that expand the antiferromagnetic phase without altering Co valence. These results demonstrate that impurity doping effectively optimizes the magnetoelectric properties of CaBaCo 4 O 7 , offering a promising strategy for enhancing the performance of polar magnetic materials.
