Electronic structure and resonant inelastic x-ray scattering in Ta2NiSe5
D. A. Kukusta, L. V. Bekenov, A. N. Yaresko +4
We study the electronic structure of Ta2NiSe5 in its low-temperature semiconducting phase, using resonant inelastic x-ray scattering (RIXS) at the Ta L3 edge. We also investigate t…
Continuum of magnetic excitations in the Kitaev honeycomb iridate DLiIrO
Thomas Halloran, Yishu Wang, K. W. Plumb +12
Inelastic neutron scattering (INS) measurements of powder DLi)(Ir)O reveal low energy magnetic excitations with a scattering cross section that is broad in…
Magnetic frustration and spontaneous rotational symmetry breaking in PdCrO2
Dan Sun, Dmitry Sokolov, Jack Bartlett +8
In the triangular layered magnet PdCrO2 the intralayer magnetic interactions are strong, however the lattice structure frustrates interlayer interactions. In spite of this, long-ra…
Ordering of hidden multipoles in spin-orbital entangled 5 Ta chlorides
Hajime Ishikawa, Tomohiro Takayama, Reinhard K. Kremer +5
Spin-orbit coupling of as large as a half eV for electrons in 5 orbitals often gives rise to the formation of spin-orbital entangled objects, characterized by the effective tota…
Pseudospin heat conductivity in the antiferromagnet SrIrO
Frank Steckel, Akiyo Matsumoto, Tomohiro Takayama +3
We report the in-plane and out-of-plane heat conductivity of the antiferromagnetic spin-orbit induced Mott insulator SrIrO with . Our data reveal clea…
Spin-orbit coupling induced semi-metallic state in the 1/3 hole doped hyper-kagome Na3Ir3O8
T. Takayama, A. Matsumoto, J. Nuss +5
The complex iridium oxide Na3Ir3O8 with a B-site ordered spinel structure was synthesized in single crystalline form, where the chiral hyper-kagome lattice of Ir atoms, as observed…
Superconductivity at 6 K and the violation of Pauli limit in Ta2PdxS5
Y. F. Lu, T. Takayama, A. F. Bangura +3
Ta2PdxS5 (x < 1.0) was found to show superconductivity at Tc ~ 6 K. The temperature dependent resistivity of single crystalline Ta2Pd0.92S5 showed that the system is strongly disor…
Metal-insulator transition and superconductivity induced by Rh doping in binary Ru Pnictides RuPn (Pn = P, As and Sb)
D. Hirai, T. Takayama, D. Hashizume +1
Binary ruthenium pnictides, RuP and RuAs, with an orthorhombic MnP structure, were found to show a metal to a non-magnetic insulator transition at TMI = 270 K and 200 K, respective…
Evidence for a correlated insulator to antiferromagnetic metal transition in CrN
P. A. Bhobe, A. Chainani, M. Taguchi +15
We investigate the electronic structure of Chromium Nitride (CrN) across the first-order magneto-structural transition at T_N ~ 286 K. Resonant photoemission spectroscopy shows a g…
Evidence for Fermi surface reconstruction in the static stripe phase of LaEuSrCuO,
V. B. Zabolotnyy, A. A. Kordyuk, D. S. Inosov +9
We present a photoemission study of LaEuSrCuO with doping level =1/8, where the charge carriers are expected to order forming static stripes. Though…
Mesoscopic Phase Coherence in a Quantum Spin Fluid
Guangyong Xu, C. Broholm, Yeong-Ah Soh +8
Mesoscopic quantum phase coherence is important because it improves the prospects for handling quantum degrees of freedom in technology. Here we show that the development of such c…
