Compass Correlations in a Square-Lattice Magnet
Otkur Omar, Matthias D. Frontzek, Gabriele Sala +14
The square-lattice compass model is a paradigm of bond-dependent frustration, yet experimental evidence for its characteristic spin correlations has remained elusive. Here we ident…
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-…
Strongly frustrated 2D magnetism in a 3D hexagonal perovskite
Bocheng Yu, Otkur Omar, Songtai Lv +12
Exotic quantum phenomena are often found to occur in spin systems that exhibit low-dimensional magnetism. By combining nuclear magnetic resonance, neutron scattering, and muon-spin…
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…
Dipolar and quadrupolar correlations in the Re-based double perovskites BaYReO and BaScReO
Otkur Omar, Yang Zhang, Qiang Zhang +8
Double perovskites containing heavy transition metal ions are an important family of compounds for the study of the interplay between electron correlation and spin-orbit coupling.…
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…
