Hidden Density-Wave Instability in the Trimer Ruthenate BaRuO
Gang Cao, Hengdi Zhao, Adrienne Bond +9
We report a hidden density-wave instability in the trimer-based ruthenate Ba4Ru3O10, previously regarded as a pure antiferromagnet with a phase transition at TA=100 K. This transit…
Spatio-temporal migration of antiferromagnetic domain walls in Sr2IrO4
Ian Robinson, David Yang, Ross Harder +18
By laser pump-probe time-resolved coherent magnetic X-ray diffraction imaging, we have measured the migration velocity of antiferromagnetic domain walls in the Mott insulator Sr2Ir…
Inductance Meets Memory in the Quantum Magnet Mn3Si2Te6
Tristan R. Cao, Gabriel Schebel, Arabella Quane +5
Orbital degrees of freedom offer a largely untapped route to emergent dynamical phenomena in correlated quantum materials. However, it remains unclear whether collective orbital st…
Magnetic excitations in the Kitaev material NaIrO studied by neutron scattering
Alexandre Bertin, Hengdi Zhao, Gang Cao +4
Inelastic neutron scattering experiments with a large set of comounted NaIrO crystals reveal the low-energy magnon dispersion in this candidate material for Kitaev physics.…
Field-Tailoring Quantum Materials via Magneto-Synthesis: Metastable Metallic and Magnetically Suppressed Phases in a Trimer Iridate
Tristan R. Cao, Hengdi Zhao, Xudong Huai +4
We demonstrate that applying modest magnetic fields during high-temperature crystal growth can profoundly alter the structure and ground state of a spin-orbit-coupled, antiferromag…
Emergent Inductance from Chiral Orbital Currents in a Bulk Ferrimagnet
Gang Cao, Hengdi Zhao, Yu Zhang +10
We report the discovery of a new form of inductance in the bulk ferrimagnet Mn3Si2Te6, which features strong spin-orbit coupling, large magnetic anisotropy, and pronounced magnetoe…
