Radiation Magnetohydrodynamic Simulations of Sub-Eddington accretion Flows in AGN: Origin of Soft X-ray Excess and Rapid Time Variabilities
Taichi Igarashi, Yoshiaki Kato, Hiroyuki R. Takahashi +3
We investigate the origin of the soft X-ray excess component in Seyfert galaxies observed when their luminosity exceeds 0.1% of the Eddington luminosity (). The e…
Absence of magnetic long range order in BaZnRuO: A spin-liquid candidate in the dimer lattice
Ichiro Terasaki, Taichi Igarashi, Takayuki Nagai +12
We have discovered a novel candidate for a spin liquid state in a ruthenium oxide composed of dimers of 3/2 spins of Ru,BaZnRuO. This compound lacks a lon…
Novel Charge Ordering in the Trimer Iridium Oxide BaIrO3
Ichiro Terasaki, Shun Ito, Taichi Igarashi +8
We have prepared polycrystalline samples of the trimer Ir oxide BaIrO3 with face-shared Ir3O12 trimers, and have investigated the origin of the phase transition at 182 K by measuri…
Unconventional magnetism in the layered oxide LaSrRhO
Noriyasu Furuta, Shinichiro Asai, Taichi Igarashi +10
We have prepared polycrystalline samples of LaSrRhGaO and LaSrCaRhO,and have measured the x-ray diffraction, resistivity, Seebeck coefficient, magne…
X-ray crystal structure analysis and the Ru valence of Ba4Ru3O10 single crystals
Taichi Igarashi, Yoshio Nogami, Yannick Klein +5
We present the single-crystalline x-ray diffraction study on the Ba4Ru3O10 consisting of the corner-shared Ru3O12 trimers. The crystal structure is re-determined from 78 to 300 K a…
