Quantum criticality in a three dimensional spin system at zero field and pressure
K. Yu. Povarov, A. Mannig, G. Perren +4
We report spontaneous appearance of antiferromagnetic order in a model gapped quantum paramagnet Ni(ClBr)4SC(NH) induced by a change in bromine conce…
Finite-temperature correlations in a quantum spin chain near saturation
Dominic Blosser, Noam Kestin, Kirill Yu. Povarov +4
Inelastic neutron-scattering and finite-temperature density matrix renormalization group (DMRG) calculations are used to investigate the spin excitation spectrum of the Hei…
High pressure Raman study of the quantum magnet (CHN)CuCl
Simon Bettler, Gediminas Simutis, Gérard Perren +3
Magnetic and lattice excitations in the quantum antiferromagnet (CHN)CuCl (PHCC) are studied across two pressure-induced phase transition at $P_c=4.3~\mathrm…
Anisotropic magnetic interactions and spin dynamics in the spin-chain compound Cu(py)Br: An experimental and theoretical study
J. Zeisner, M. Brockmann, S. Zimmermann +9
We compare theoretical results for electron spin resonance (ESR) properties of the Heisenberg-Ising Hamiltonian with ESR experiments on the quasi-one-dimensional magnet Cu(py)B…
Novel Crossover in Coupled Spin Ladders
M. Jeong, H. Mayaffre, C. Berthier +3
We report a novel crossover behavior in the long-range-ordered phase of a prototypical spin- Heisenberg antiferromagnetic ladder compound . The…
