Phase diagram of the alternating-spin Heisenberg chain with extra isotropic three-body exchange interactions
N. B. Ivanov, J. Ummethum, J. Schnack
For the time being isotropic three-body exchange interactions are scarcely explored and mostly used as a tool for constructing various exactly solvable one-dimensional models, alth…

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…
