Elementary magnons and interacting multi-magnon quasiparticles in the effective spin- kagome-staircase magnet CoVO

Yuan Xiao, Jiajun Mo, Zhenmeng Jiang +6

The excitation spectrum of an anisotropic magnet provides a direct link between its microscopic Hamiltonian and interaction-driven quasiparticles. Here we use high-resolution time-…

Emergent Vortex Ordering in a Multiflavor Pyrochlore-Lattice Compound GeCoO

Jiajun Mo, Otkur Omar, Shuangkui Guang +12

Entangled spin and orbital degrees of freedom provide a multiflavor route to novel magnetic states inaccessible in conventional spin systems. Here, we report the experimental ident…

Codimension-Two Spiral Spin-Liquid in the Effective Honeycomb-Lattice Compound CsFeCl

Shang Gao, Chris Pasco, Otkur Omar +7

A codimension-two spiral spin-liquid is a correlated paramagnetic state with one-dimensional ground state degeneracy hosted within a three-dimensional lattice. Here, via neutron sc…

Nematic quantum disordered state in FeSe

Ruixian Liu, Matthew B. Stone, Shang Gao +9

The unusual quantum-disordered magnetic ground state intertwined with superconductivity and electronic nematicity in FeSe has been a research focus in iron-based superconductors. H…
