Microscopic investigation of spin dynamics in the single-chain magnet Sr4Mn2CoO9
G. Roy, S. Ghosh, M. Kumar +8
One-dimensional single-chain magnets offer a unique platform for studying the interplay of crystal-field effects, exchange interactions, and lattice dynamics. Here, we investigate…
Field-induced quasi-bound state within the two-magnon continuum of a square-lattice Heisenberg antiferromagnet
F. Elson, M. Nayak, A. A. Eberharter +14
Quantum magnets in two dimensions display strong quantum interaction effects even when magnetically ordered. Using the metal-organic framework material CuF(DO)(pyz), we…
Intrinsic disorder in the candidate quantum spin ice PrZrO
T. J. Hicken, P. Meadows, D. Prabhakaran +13
Quantum spin liquids with long-range entanglement are of great interest for applications in quantum technology. The quantum spin ice PrZrO is a promising example, where…
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…
The nature of dynamic local order in CHNHPbI and CHNHPbBr
Nicholas Weadock, Tyler Sterling, Julian Vigil +12
Hybrid lead halide perovskites (LHPs) are a class of semiconductor with novel properties that are distinctively governed by structural fluctuations. Diffraction experiments sensiti…
Emergent many-body composite excitations of interacting spin-1/2 trimers
A. K. Bera, S. M. Yusuf, S. K. Saha +4
Understanding exotic forms of magnetism in quantum spin systems is an emergent topic of modern condensed matter physics. Quantum dynamics can be described by particle-like carriers…
