| Research Abstract |
We have developed real space imaging techniques in high magnetic fields, such as scanning tunneling microscopy (STM), magneto-optical imaging, scanning Hall probe microscopy and electron spin polarization imaging. We have first succeeded in the STM operation up to 27 T in the hybrid magnet and in the highly-stable operation up to 11 T in the superconducting magnet. These techniques have been applied to investigate electronic and magnetic states in novel superconductors and magnetic materials and also electron density distribution in a 2D-electron system.
