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…
Photovoltaic effect by soft phonon excitation
Yoshihiro Okamura, Takahiro Morimoto, Naoki Ogawa +7
Photodetection is an indispensable function of optoelectronic devices in modern communication and sensing systems. Contrary to the near-infrared/visible regions, the fast and sensi…
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…
Robust noncoplanar magnetism in band filling-tuned (NdCa)MoO
Max Hirschberger, Yoshio Kaneko, Leonie Spitz +3
In the metallic pyrochlore NdMoO, the conducting Molybdenum sublattice adopts canted, yet nearly collinear ferromagnetic order with nonzero scalar spin chirality. The c…
Strong magneto-optical effects in ACr2O4 A=Fe, Co spinel oxides generated by tetrahedrally coordinated transition metal ions
Vilmos Kocsis, Sándor Bordács, Joachim Deisenhofer +5
Magneto-optical effects have been investigated over the infrared{visible spectral range in ACr2O4 (A = Fe, Co) spinel oxides with non-collinear spin orders in their ground states.…
Geometrical Hall effect and momentum-space Berry curvature from spin-reversed band pairs
Max Hirschberger, Yusuke Nomura, Hiroyuki Mitamura +10
When nanometric, noncoplanar spin textures with scalar spin chirality (SSC) are coupled to itinerant electrons, they endow the quasiparticle wavefunctions with a gauge field, terme…
