Highly anisotropic geometrical Hall effect via f-d exchange fields in doped pyrochlore molybdates

Hikaru Fukuda, Kentaro Ueda, Yoshio Kaneko +6

When a conduction electron couples with a non-coplanar localized magnetic moment, the realspace Berry curvature is exerted to cause the geometrical Hall effect, which is not simply…

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…

Berry curvature generation detected by Nernst responses in ferroelectric Weyl semimetal

Cheng-Long Zhang, Tian Liang, M. S. Bahramy +6

The quest for nonmagnetic Weyl semimetals with high tunability of phase has remained a demanding challenge. As the symmetry breaking control parameter, the ferroelectric order can…

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…
