Half-ordered state in the anisotropic Haldane-gap antiferromagnet NDMAP
A. Zheludev, B. Grenier, E. Ressouche +2
Neutron diffraction experiments performed on the Haldane gap material NDMAP in high magnetic fields applied at an angle to the principal anisotropy axes reveal two consecutive fiel…
Structural, transport, and thermal properties of single crystalline type-VIII clathrate Ba8Ga16Sn30
D. Huo, T. Sakata, T. Sasakawa +7
We report the electrical resistivity, Hall coefficient, thermoelectric power, specific heat, and thermal conductivity on single crystals of the type-VIII clathrate Ba8Ga16Sn30 grow…
Charge-Order Pattern of the Low-Temperature Phase of NaV2O5 Uniquely Determined by Resonant X-Ray Scattering from Monoclinic Single Domain
Kenji Ohwada, Yasuhiko Fujii, Yuya Katsuki +7
The present resonant x-ray scattering from each of monoclinically-split single domains of NaV2O5 has critically enhanced contrast between V4+ and V5+ ions strong enough to lead to…
Laser-excited ultrahigh-resolution photoemission spectroscopy of NaxCoO2.yH2O:Evidence for pseudogap formation
T. Shimojima, T. Yokoya, T. Kiss +9
We have studied the temperature-dependent electronic structure near the Fermi level (EF) of the layered cobaltate superconductor, Na0.35CoO2.1.3H2O, and related materials, using la…
High-energy photoemission on Fe3O4: Small polaron physics and the Verwey transition
D. Schrupp, M. Sing, M. Tsunekawa +7
We have studied the electronic structure and charge ordering (Verwey) transition of magnetite (Fe3O4) by soft x-ray photoemission. Due to the enhanced probing depth and the use of…
Nature of Well-Screened State in Hard X-ray Mn 2 Core-Level Photoemission of LaSrMnO Films
K. Horiba, M. Taguchi, A. Chainani +17
Using hard x-ray (HX ; = 5.95 keV) synchrotron photoemission spectroscopy (PES), we study the intrinsic electronic structure of LaSrMnO (LSMO) thin films. Comp…
