Research Abstract

We have obtained new findings on materials in regulated nano-spaces such as zeorite and carbon nanotubes by the measurements in high magnetic fields or high pressure. Electron spin resonance and high-field magnetization of these materials were measured and intriguing magnetic states were observed. As for Fe-based high-Tc materials, upper critical fields and relationship between structure and electronic nature were investigated.
