Defect-induced optical magnons and local magnetic correlations in MnSb2Te4
Dhurba R. Jaishi, Bing Li, Tianxiong Han +4
Magnetic defect engineering offers a route to manipulate and control magnetic and electronic states in quantum materials. In the Mn(Bi,Sb)2Te4 family of topological magnetic insula…
Chiral Magnon Mixing by Symmetry-Breaking in Collinear Ferrimagnets
Dhurba R. Jaishi, Tyler J. Slade, S. X. M. Riberolles +8
Magnons in ferromagnets possess spin angular momentum defined by right-handed precession of the moment around the magnetization direction. In antiferromagnets with no net magnetiza…
Spectrum and low-temperature bulk properties of triangular quantum spin liquid candidate NaYbSe
A. O. Scheie, Minseong Lee, Kevin Wang +18
We report neutron scattering, pressure-dependent AC calorimetry, and AC magnetic susceptibility measurements of triangular lattice NaYbSe. We observe a continuum of scattering,…
Quantifying the Phase Diagram and Hamiltonian of Kagome Antiferromagnets: Bridging Theory and Experiment
Shengtao Jiang, Arthur C. Campello, Wei He +4
Spin- kagome antiferromagnets are leading candidates for realizing quantum spin liquid (QSL) ground states. While QSL ground states are predicted for the pure Heisenberg model…
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…
Coupled sawtooth chain exchange network in olivine MnGeO
Vincent C. Morano, Zeno Maesen, Stanislav Nikitin +6
Sawtooth chain magnets have been a subject of historical interest in the field of frustrated magnetism, with classical olivine family , ( - 3d, - 4p, - chalcoge…
