Observation of 4- and 6-magnon bound-states in the spin-anisotropic frustrated antiferromagnet FeI
Anaëlle Legros, Shang-Shun Zhang, Xiaojian Bai +6
Spin-waves e.g. magnons are the conventional elementary excitations of ordered magnets. However, other possibilities exist. For instance, magnon bound-states can arise due to attra…
Neutron scattering investigation of proposed Kosterlitz-Thouless transitions in the triangular-lattice Ising antiferromagnet TmMgGaO4
Zhiling Dun, Marcus Daum, Raju Baral +10
The transverse-field Ising model on the triangular lattice is expected to host an intermediate finite-temperature Kosterlitz-Thouless (KT) phase through a mapping of the spins on e…
Magnetic Field Induced Phase Transition in Spinel GeNi2O4
T. Basu, T. Zou, Z. Dun +7
Cubic spinel GeNi2O4 exhibits intriguing magnetic properties with two successive antiferromagnetic phase transitions (TN1 12.1 and TN2 11.4 K) with the absence of any structural tr…
Hybridized quadrupolar excitations in the spin-anisotropic frustrated magnet FeI2
Xiaojian Bai, Shang-Shun Zhang, Zhiling Dun +8
Magnetic order is usually associated with well-defined magnon excitations. Exotic magnetic fluctuations with fractional, topological or multipolar character, have been proposed for…
Effective point-charge analysis of crystal electric fields -- application to rare-earth pyrochlores and tripod kagome magnets R3Mg2Sb3O14
Zhiling Dun, Xiaojian Bai, Matthew B. Stone +2
An indispensable step to understand collective magnetic phenomena in rare-earth compounds is the determination of spatially-anisotropic single-ion properties resulting from spin-or…
Unraveling the Topological Phase of ZrTe via Magneto-infrared Spectroscopy
Y. Jiang, J. Wang, T. Zhao +9
For materials near the phase boundary between weak and strong topological insulators (TIs), their band topology depends on the band alignment, with the inverted (normal) band corre…
Noncollinear magnetic structure and magnetoelectric coupling in buckled honeycomb CoNbO:A single crystal neutron diffraction study
Lei Ding, Minseong Lee, Tao Hong +8
Through analysis of single crystal neutron diffraction data, we present the magnetic structures of magnetoelectric Co4Nb2O9 under various magnetic fields. In zero-field, neutron di…
