Song, G. S., Kobayashi, M., Hwang, J. I., Kataoka, T., Takizawa, M., Fujimori, A., ...
The electronic structure of the magnetic semiconductor Ga$_{1-x}$Cr$_{x}$N and the effect of Si doping on it have been investigated by photoemission and soft x-ray absorption spectroscopy. We have...
Hwang, J. I., Kobayashi, M., Song, G. S., Fujimori, A., Tanaka, A., Yang, Z. S., ...
We have investigated the magnetic properties of a GaN/Ga1-xMnxN (x = 0.1) digital ferromagnetic heterostructure (DFH) showing ferromagnetic behavior using soft x-ray absorption spectroscopy (XAS) and...
Symmetry of Multiferroicity in a Frustrated Magnet TbMn$_2$O$_5$ (2007)
Okamoto, J., Huang, D. J., Mou, C. -Y., Chao, K. S., Lin, H. -J., Park, S., ...
Based on measurements of soft x-ray magnetic scattering and symmetry considerations, we demonstrate that the magnetoelectric effect in TbMn$_2$O$_5$ arises from an internal field determined by...
Orbital Symmetry and Electron Correlation in Na_{x}CoO_2 (2004)
Wu, W. B., Huang, D. J., Okamoto, J., Tanaka, A., Lin, H. -J., Chou, F. C., ...
Measurements of polarization-dependent soft x-ray absorption reveal that the electronic states determining the low-energy excitations of Na$_{x}$CoO$_2$ have predominantly $a_{1g}$ symmetry with...
Nature of Orbital Ordering in La_0.5Sr_1.5MnO_4 is Studied by Soft X-ray Linear Dichroism (2003)
Huang, D. J., Wu, W. B., Guo, G. Y., Lin, H-J, Hou, T. Y., Chang, C. F., ...
We found that the conventional model of orbital ordering of 3x^2-r^2/3y^2-r^2 type in the eg states of La_0.5Sr_1.5MnO_4 is incompatible with measurements of linear dichroism in the Mn 2p-edge x-ray...
Experimental evidence of the spin selection rule in KLL Auger transition (2001)
Huang, D. J., Wu, W. P., Chang, C. F., Chen, J., Chung, S. C., Tjeng, L. H., ...
With on- and off- resonant excitation photons, spin-resolved Auger electron spectra of epitaxial CrO$_{2}$ thin films show an experimental evidence of the spin-selective KLL Auger decay. The...
