Quantum Spin Dynamics Due to Strong Kitaev Interactions in the Triangular-Lattice Antiferromagnet CsCeSe
Tao Xie, S. Gozel, Jie Xing +8
The extraordinary properties of the Kitaev model have motivated an intense search for new physics in materials that combine geometrical and bond frustration. In this work, we emplo…
Stripe magnetic order and field-induced quantum criticality in the perfect triangular-lattice antiferromagnet CsCeSe
Tao Xie, Nan Zhao, S. Gozel +13
The two-dimensional triangular-lattice antiferromagnet (TLAF) is a textbook example of frustrated magnetic systems. Despite its simplicity, the TLAF model exhibits a highly rich an…
Magnetic field-induced phases and spin Hamiltonian in Cs2CoBr4
L. Facheris, S. D. Nabi, K. Yu. Povarov +12
Magnetic structures and spin excitations are studied across the phase diagram of the geometrically frustrated S = 3/2 quantum antiferromagnet Cs2CoBr4 in magnetic fields applied al…
Quantum Spin Ice Response to a Magnetic Field in the Dipole-Octupole Pyrochlore CeZrO
E. M. Smith, J. Dudemaine, B. Placke +17
We report new heat capacity measurements on single crystal CeZrO down to 0.1 K in a magnetic field along the direction. These new measurements s…
Bose-Einstein condensation of a two-magnon bound state in a spin-one triangular lattice
Jieming Sheng, Jia-Wei Mei, Le Wang +31
In ordered magnets, the elementary excitations are spin waves (magnons), which obey Bose-Einstein statistics. Similarly to Cooper pairs in superconductors, magnons can be paired in…
Continuous spin excitations in the three-dimensional frustrated magnet K2Ni2(SO4)3
Weiliang Yao, Qing Huang, Tao Xie +12
Continuous spin excitations are widely recognized as one of the hallmarks of novel spin states in quantum magnets, such as quantum spin liquids (QSLs). Here, we report the observat…
Diffusive Excitonic Bands from Frustrated Triangular Sublattice in a Singlet-Ground-State System
Bin Gao, Tong Chen, Xiao-Chuan Wu +17
Magnetic order in most materials occurs when magnetic ions with finite moments in a crystalline lattice arrange in a particular pattern below the ordering temperature determined by…
