Syntheses and First-Principles Calculations of the Pseudobrookite Compound AlTi2O5
Takami Tohyama, Riku Ogura, Kensuke Yoshinaga +3
We synthesize a new titanium-oxide compound AlTi2O5 with pseudobrookite-type structure. The formal valence of Ti is 3.5+ that is the same as the Magneli compound Ti4O7 and the spin…
Origin of in-plane anisotropic resistivity in the antiferromagnetic phase of FeTe
Eiji Kaneshita, Takami Tohyama
Motivated by a recent experimental report on in-plane anisotropic resistivity in the double-striped antiferromagnetic phase of FeTe, we theoretically calculate in-plane resistivity…
Orbital-selective electronic excitations in iron arsenides revealed by simulated nonresonant inelastic x-ray scattering
Kenji Tsutsui, Eiji Kaneshita, Takami Tohyama
Nonresonant inelastic x-ray scattering (NIXS) is a possible tool to detect charge excitations in electron systems. In addition, multipole transitions at high-momentum-transfer regi…
Spin Dynamics and Resonant Inelastic X-ray Scattering in Chromium with Commensurate Spin-Density Wave Order
Koudai Sugimoto, Zhi Li, Eiji Kaneshita +2
We theoretically investigate spin dynamics and -edge resonant inelastic X-ray scattering (RIXS) of Chromium with commensurate spin-density wave (SDW) order, based on a multi-b…
Analysis of Resonant Inelastic X-Ray Scattering in Stripe-Ordered Nickelate
Takuji Nomura, Eiji Kaneshita
We analyze theoretically the resonant inelastic x-ray scattering (RIXS) at the Ni K edge in the stripe-ordered state of La_{2-x}Sr_xNiO_4 at x=1/3. In the calculation of RIXS spect…
Spin and Orbital Characters of Excitations in Iron Arsenide Superconductors Revealed by Simulated Fe L-Edge RIXS
E. Kaneshita, K. Tsutsui, T. Tohyama
We theoretically examine the orbital excitations coupled to the spin degree of freedom in the parent state of the iron-arsenide superconductor, based on the calculation in a five-b…
