General Magnetic Transition Dipole Moments for Electron Paramagnetic Resonance
Joscha Nehrkorn, Alexander Schnegg, Karsten Holldack +1
We present general expressions for the magnetic transition rates in beam Electron Paramagnetic Resonance (EPR) experiments of anisotropic spin systems in the solid state. The expre…
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…
Staying adiabatic with unknown energy gap
J. Nehrkorn, S. Montangero, A. Ekert +3
We introduce an algorithm to perform an optimal adiabatic evolution that operates without an apriori knowledge of the system spectrum. By probing the system gap locally, the algori…
Inelastic neutron scattering study and Hubbard model description of the antiferromagnetic tetrahedral molecule Ni4Mo12
J. Nehrkorn, M. Höck, M. Brüger +3
The tetrameric Ni(II) spin cluster Ni4Mo12 has been studied by INS. The data were analyzed extensively in terms of a very general spin Hamiltonian, which includes antiferromagnetic…
