Systematic changes of the electronic structure of the diluted ferromagnetic oxide Li-doped Ni$_{1-x}$Fe$_x$O with hole doping (2007)

Kobayashi, M., Hwang, J. I., Song, G. S., Ooki, Y., Takizawa, M., Fujimori, A., ...

The electronic structure of Li-doped Ni$_{1-x}$Fe$_x$O has been investigated using photoemission spectroscopy (PES) and x-ray absorption spectroscopy (XAS). The Ni $2p$ core-level PES and XAS spectra...

Depth profile photoemission study of thermally diffused Mn/GaAs (001) interfaces (2007)

Osafune, Y., Song, G. S., Hwang, J. I., Ishida, Y., Kobayashi, M., Ebata, K., ...

We have performed a depth profile study of thermally diffused Mn/GaAs (001) interfaces using photoemission spectroscopy combined with Ar$^+$-ion sputtering. We found that Mn ion was thermally...

Photoemission and x-ray absorption studies of valence states in (Ni,Zn,Fe,Ti)$_{3}$O$_{4}$ thin films exhibiting photo-induced magnetization (2007)

Kobayashi, M., Ooki, Y., Takizawa, M., Song, G. S., Fujimori, A., Takeda, Y., ...

By means of photoemission and x-ray absorption spectroscopy, we have studied the electronic structure of (Ni,Zn,Fe,Ti)$_{3}$O$_{4}$ thin films, which exhibits a cluster glass behavior with a...

Depth profile high-energy spectroscopic study of Mn-doped GaN prepared by thermal diffusion (2007)

Hwang, J. I., Osafune, Y., Kobayashi, M., Ebata, K., Ooki, Y., Ishida, Y., ...

We have performed an $in$-$situ$ depth profile study of Mn-doped GaN prepared by a low temperature thermal diffusion method using photoemission and x-ray absorption spectroscopy. It was revealed from...
