Observation of plaquette fluctuations in the spin-1/2 honeycomb lattice
C. Wessler, B. Roessli, K. W. Krämer +6
Quantum spin liquids are materials that feature quantum entangled spin correlations and avoid magnetic long-range order at T = 0 K. Particularly interesting are two-dimensional hon…
The even-odd effect in short antiferromagnetic Heisenberg chains
A. Machens, N. P. Konstantinidis, O. Waldmann +2
Motivated by recent experiments on chemically synthesized magnetic molecular chains we investigate the lowest lying energy band of short spin- antiferromagnetic Heisenberg chain…
Discrete antiferromagnetic spin-wave excitations in the giant ferric wheel Fe18
J. Ummethum, J. Nehrkorn, S. Mukherjee +8
The low-temperature elementary spin excitations in the AFM molecular wheel Fe18 were studied experimentally by inelastic neutron scattering and theoretically by modern numerical me…
High-Frequency Electron-Spin-Resonance Study of the Octanuclear Ferric Wheel CsFe
Jan Dreiser, Oliver Waldmann, Graham Carver +4
High-frequency ( = 190 GHz) electron paramagnetic resonance (EPR) at magnetic fields up to 12 T as well as Q-band ( = 34.1 GHz) EPR were performed on single crystals of the m…
Spin-Peierls instabilities of antiferromagnetic rings in a magnetic field
Valeria Lante, Ioannis Rousochatzakis, Karlo Penc +2
Motivated by the intriguing properties of magnetic molecular wheels at field induced level crossings, we investigate the spin-Peierls instability of antiferromagnetic rings in a fi…
Direct observation of mixing of spin-multiplets in an antiferromagnetic molecular nanomagnet by electron paramagnetic resonance
S. Datta, O. Waldmann, A. D. Kent +3
High-frequency electron paramagnetic resonance (EPR) studies of the antiferromagnetic Mn- molecular grid clearly reveal a breaking of the selection rule, prov…
