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…
Quantized antiferromagnetic spin waves in the molecular Heisenberg ring CsFe
J. Dreiser, O. Waldmann, C. Dobe +7
We report on inelastic neutron scattering (INS) measurements on the molecular spin ring CsFe, in which eight spin-5/2 Fe(III) ions are coupled by nearest-neighbor antiferromagn…
Quantum dynamics of the Neel vector in the antiferromagnetic molecular wheel CsFe8
O. Waldmann, C. Dobe, H. U. Güdel +1
The inelastic neutron scattering (INS) spectrum is studied for the antiferromagnetic molecular wheel CsFe8, in the temperature range 2 - 60 K, and for transfer energies up 3.6 meV.…
Magnetic relaxation studies on a single-molecule magnet by time-resolved inelastic neutron scattering
O. Waldmann, G. Carver, C. Dobe +6
Time-resolved inelastic neutron scattering measurements on an array of single-crystals of the single-molecule magnet Mn12ac are presented. The data facilitate a spectroscopic inves…
Field-induced magnetoelastic instabilities in antiferromagnetic molecular wheels
O. Waldmann, C. Dobe, S. T. Ochsenbein +2
The magnetic torque of the antiferromagnetic molecular wheel CsFe8 was studied down to 50 mK and in fields up to 28 T. Below ca. 0.5 K phase transitions were observed at the field-…
Mesoscopic quantum coherence in antiferromagnetic molecular clusters
O. Waldmann, C. Dobe, H. Mutka +2
From inelastic neutron scattering experiments, we demonstrate quantum tunneling of the Neel vector in the antiferromagnetic molecular ferric wheel CsFe8. Analysis of the linewidth…
