Measuring the orbital angular momentum of electron vortex beams using a forked grating
Koh Saitoh, Yuya Hasegawa, Kazuma Hirakawa +2
The present study experimentally examines how an electron vortex beam with orbital angular momentum (OAM) undergoes diffraction through a forked grating. The nth-order diffracted e…
Epitaxially stabilized iridium spinel oxide without cations in the tetrahedral site
Hiromichi Kuriyama, Jobu Matsuno, Seiji Niitaka +7
Single-crystalline thin film of an iridium dioxide polymorph Ir2O4 has been fabricated by the pulsed laser deposition of LixIr2O4 precursor and the subsequent Li-deintercalation us…
Band Jahn-Teller Instability and Formation of Valence Bond Solid in a Mixed-Valent Spinel Oxide LiRh2O4
Yoshihiko Okamoto, Seiji Niitaka, Masaya Uchida +7
We have synthesized a new spinel oxide LiRh2O4 with a mixed-valent configuration of Rh3+ and Rh4+. At room temperature it is a paramagnetic metal, but on cooling, a metal-insulator…
Variation of charge/orbital ordering in layered manganites Pr1-xCa1+xMnO4 investigated by transmission electron microscopy
X. Z. Yu, R. Mathieu, T. Arima +9
Structural features of the charge/orbital ordering (CO/OO) in single-layered manganites Pr1-xCa1+xMnO4 have been investigated systematically by transmission electron microscopy. An…
Coexistence of long-ranged charge and orbital order and spin-glass state in single-layered manganites with weak quenched disorder
R. Mathieu, J. P. He, X. Z. Yu +6
The relationship between orbital and spin degrees of freedom in the single-crystals of the hole-doped PrCaMnO, 0.3 0.7, has been investigated…
Non-cubic layered structure of Ba(1-x)K(x)BiO3 superconductor
L. A. Klinkova, M. Uchida, Y. Matsui +2
Bismuthate superconductor Ba(1-x)K(x)BiO3 (x=0.27-0.49, Tc=25-32K) grown by an electrolysis technique was studied by electron diffraction and high-resolution electron microscopy. T…
