Observation of complex orbital order in MnV2O4
Chihaya Koyama, Shunsuke Kitou, Taishun Manjo +8
Orbital ordering in vanadium spinel oxides with a geometrically frustrated pyrochlore structure has been a subject of controversy, owing to competing theoretical models and the abs…
Electronic States and Possible Origin of the Orbital-Glass State in a Nearly Metallic Spinel Cobalt Vanadate: An X-ray Magnetic Circular Dichroism Study
Yosuke Nonaka, Goro Shibata, Rui Koborinai +8
We have investigated the orbital states of the orbital-glassy (short-range orbital ordered) spinel vanadate CoVO using x-ray absorption spectroscopy (XAS),…
Time-of-flight elastic and inelastic neutron scattering studies on the localized electron layered perovskite LaMoO
K. Iida, R. Kajimoto, Y. Mizuno +11
The magnetic structure and spin-wave excitations in the quasi-square-lattice layered perovskite compound LaMoO were studied by a combination of neutron diffraction a…
A variety of elastic anomalies in orbital-active nearly-itinerant cobalt vanadate spinel
Tadataka Watanabe, Shogo Yamada, Rui Koborinai +1
We perform ultrasound velocity measurements on a single crystal of nearly-metallic spinel CoVO which exhibits a ferrimagnetic phase transition at 1…
An orbital glass state of a nearly metallic spinel, CoVO
R. Koborinai, S. E. Dissanayake, M. Reehuis +3
Strain, magnetization, and unpolarized and polarized neutron diffraction measurements were performed to study the magnetic and structural properties of spinel CoVO. Mag…
Intrinsic Structural Disorder and the Magnetic Ground State in Bulk EuTiO3
A. P. Petrovic, Y. Kato, S. S. Sunku +8
The magnetic properties of single-crystal EuTiO3 are suggestive of nanoscale disorder below its cubic-tetragonal phase transition. We demonstrate that electric field cooling acts t…
On the role of intrinsic disorder in the structural phase transition of magnetoelectric EuTiO3
Mattia Allieta, Marco Scavini, Leszek Spalek +6
Up to now the crystallographic structure of the magnetoelectric perovskite EuTiO3 was considered to remain cubic down to low temperature. Here we present high resolution synchrotro…
Raman scattering due to a one-magnon excitation process in
S. Miyahara, K. Takubo, T. Suzuki +2
Unconventional peak structure in the Raman spectra due to magnon excitation at low temperature is observed in spinel magnet , where a noncollinear spin state is rea…
Electronic Structure of Charge- and Spin-controlled Sr_{1-(x+y)}La_{x+y}Ti_{1-x}Cr_{x}O_{3}
H. Iwasawa, K. Yamakawa, T. Saitoh +6
We present the electronic structure of Sr_{1-(x+y)}La_{x+y}Ti_{1-x}Cr_{x}O_{3} investigated by high-resolution photoemission spectroscopy. In the vicinity of Fermi level, it was fo…
Charge dynamics and "ferromagnetism" of A1-xLaxB6 (A=Ca and Sr)
K. Taniguchi, T. Katsufuji, F. Sakai +3
Ferromagnetism has been reported recently in La-doped alkaline-earth hexaborides, A1-xLaxB6 (A=Ca, Sr, and Ba). We have performed the reflectivity, Hall resistivity, and magnetizat…

R. Kajimoto, T. Kakeshita, H. Yoshizawa +3
Ordering process of stripe order in La{2-x}Sr{x}NiO{4} with x being around 1/3 was investigated by neutron diffraction experiments. When the stripe order is formed at high temperat…
