Experimental signatures of versatile Weyl semimetal in pyrochlore iridate with spin-ice like magnetic orders
Kentaro Ueda, Hiroaki Ishizuka, Markus Kriener +6
We report experimental signatures of topological transitions among the Weyl semimetal states of pyrochlore Pr2Ir2O7, where the Kondo coupling between the Ir topological electrons a…
Fully filling-controlled pyrochlore ruthenates: emergent ferromagnetic-metal state and geometrical Hall effect
Ryoma Kaneko, Kentaro Ueda, Shiro Sakai +4
Carrier doping to the Mott insulator is essential to produce highly correlated metals with emergent properties. Pyrochlore ruthenates, PrRuO (Ru- electron num…
Evolution of possible Weyl semimetal states across the hole-doping induced Mott transition in pyrochlore iridates
Kentaro Ueda, Hikaru Fukuda, Ryoma Kaneko +2
We study possible Weyl semimetals of strongly-correlated electrons by investigating magnetotransport properties in pyrochlore R2Ir2O7 (R=rare-earth ions), choosing three types of R…
Spin-wave gap collapse in Rh-doped Sr2IrO4
J. Bertinshaw, J. K. Kim, J. Porras +7
We use resonant inelastic x-ray scattering (RIXS) at the Ir L3 edge to study the effect of hole doping upon the Jeff=1/2 Mott-insulating state in Sr2IrO4, via Rh replacement of the…
Observation of spin-orbit excitations and Hund's multiplets in CaRuO
H. Gretarsson, H. Suzuki, Hoon Kim +6
We use Ru -edge (2838.5 eV) resonant inelastic x-ray scattering (RIXS) to quantify the electronic structure of CaRuO, a layered -electron compound that exhibits a…
Spin-orbit-controlled metal-insulator transition in SrIrO
Berend Zwartsenberg, Ryan P. Day, Elia Razzoli +12
In the context of correlated insulators, where electron-electron interactions (U) drive the localization of charge carriers, the metal-insulator transition (MIT) is described as ei…
Pressure and magnetic-field effects on metal-insulator transitions of bulk and domain-wall states in pyrochlore iridates
K. Ueda, J. Fujioka, C. Terakura +1
We have explored the critical metal-insulator phenomena for pyrochlore-type IrO, in which electron correlation strength and magnetic configuration are systematically c…
Impact of geometrical frustration on charge transport near the Mott transition in pyrochlore (YCd)MoO
S. Iguchi, Y. Kumano, K. Ueda +2
To search for novel spin-charge coupled phenomena in the strongly correlated electron system on a frustration lattice, charge transport and dynamics have been investigated for the…
