Okuyama, D., Nakamura, M., Wakabayashi, Y., Itoh, H., Kumai, R., Yamada, H., ...
Effect of growth orientation on charge- and orbital-ordering (CO-OO) phenomena has been studied for Pr0.5Ca0.5MnO3 epitaxial thin films fabricated on (LaAlO3)0.3-(SrAl0.5Ta0.5O3)0.7 (LSAT) substrates...
Okuyama, D., Tokunaga, Y., Kumai, R., Taguchi, Y., Arima, T., Tokura, Y.
The orbital shapes and charge disproportionations at nominal Mn$^{3+}$ and Mn$^{4+}$ sites for the charge- and orbital-ordered phases have been studied on half-doped manganites...
Frustration-driven successive metamagnetic transitions in TbB4 (2007)
Inami, T., Ohwada, K., Matsuda, Y. H., Ouyang, Z. W., Nojiri, H., Okuyama, D., ...
Resonant magnetic x-ray diffraction experiments on the Shastry-Sutherland lattice TbB$_4$ were carried out under strong pulsed magnetic fields up to 30 T. TbB$_4$ exhibits a multi-step magnetization...
