Bulk Nature of Layered Perovskite Iridates beyond the Mott Scenario : An Approach from Bulk Sensitive Photoemission Study
A. Yamasaki, S. Tachibana, H. Fujiwara +24
We present genuine bulk Ir 5d jeff states of layered perovskite iridates obtained by hard-x-ray photoemission spectroscopy (HAXPES) with s- and p-polarized lights. HAXPES spectra o…
Emergence of highly degenerate excited states in frustrated magnet MgCrO
K. Tomiyasu, T. Yokobori, Y. Kousaka +5
High degeneracy in ground states leads to the generation of exotic zero-energy modes, a representative example of which is the formation of molecular spin liquid-like fluctuations…
Inelastic neutron scattering study of phonons and magnetic excitations in LaCoO
Y. Kobayashi, Thant Sin Naing, M. Suzuki +7
We have investigated the phonon and the magnetic excitations in LaCoO3 by inelastic neutron scattering measurements. The acoustic phonon dispersions show some characteristic featur…
Anisotropic Charge Modulation in Ladder Planes of Sr_14-xCa_xCu_24O_41
T. Vuletic, T. Ivek, B. Korin-Hamzic +7
The charge response of the ladders in Sr_14-xCa_xCu_24O_41 is characterized by dc resistivity, low frequency dielectric and optical spectroscopy in all three crystallographic direc…
High-Resolution Photoemission Study of MgB2
T. Takahashi, T. Sato, S. Souma +2
We have performed high-resolution photoemission spectroscopy on MgB2 and observed opening of a superconducting gap with a narrow coherent peak. We found that the superconducting ga…
The role of single-ion excitations in the mixed-spin quasi-1-dimensional quantum antiferromagnet Nd_2BaNiO_5
A. Zheludev, S. Maslov, T. Yokoo +4
Inelastic neutron scattering experiments on Nd2BaNiO5 single-crystals and powder samples are used to study the dynamic coupling of 1-dimensional Haldane-gap excitations in the S=1…
