Magnetic excitation spectrum and Hamiltonian of the quantum spin chain BaCuTe2O6
A. Samartzis, S. Chillal, H. O. Jeschke +4
The magnetic excitation spectrum and Hamiltonian of the quantum magnet BaCuTe2O6 is studied by inelastic neutron scattering (INS) and density functional theory (DFT). INS on powder…
Spin-wave directional anisotropies in antiferromagnetic BaNbFeSiO
C. Stock, R. D. Johnson, N. Giles-Donovan +14
BaNbFeSiO (langasite) is structurally and magnetically single domain chiral with the magnetic helicity induced through competing symmetric exchange interac…
Ba8MnNb6O24: a model two-dimensional spin-5/2 triangular lattice antiferromagnet
R. Rawl, L. Ge, Z. Lu +8
We successfully synthesized and characterized the triangular lattice anitferromagnet BaMnNbO, which comprises equilateral spin-5/2 Mn triangular layers separa…
Lattice distortion effects on the frustrated spin-1 triangular-antiferromagnet A3NiNb2O9 (A = Ba, Sr and Ca)
Z. Lu, L. Ge, G. Wang +6
In the geometrically frustrated materials with the low-dimensional and small spin moment, the quantum fluctuation could interfere with the complicated interplay of the spin, electr…
Landau level spectroscopy of massive Dirac fermions in single-crystalline ZrTe5 thin flakes
Y. Jiang, Z. L. Dun, H. D. Zhou +8
We report infrared magneto-spectroscopy studies on thin crystals of an emerging Dirac material ZrTe5 near the intrinsic limit. The observed structure of the Landau level transition…
The nature of spin excitations in the one-third magnetization plateau phase of BaCoSbO
Y. Kamiya, L. Ge, Tao Hong +10
Magnetization plateaus in quantum magnets---where bosonic quasiparticles crystallize into emergent spin superlattices---are spectacular yet simple examples of collective quantum ph…
