Phys. Rev. B 62, 3018–3021 (2000)High-frequency resonant experiments in Fe8 molecular clustersReceived 19 April 2000; published in the issue dated 1 August 2000 Precise resonant experiments on Fe8 magnetic clusters have been conducted down to 1.2 K at various tranverse magnetic fields, using a cylindrical resonator cavity with 40 different frequencies between 37 and 110 GHz. All the observed resonances for both single crystal and oriented powder have been fitted by the eigenstates of the Hamiltonian H=-DSz2+ESx2-gμBH⋅S+C(S+4+S-4). We have identified the resonances corresponding to the coherent quantum oscillations for different orientations of spin S=10. © 2000 The American Physical Society URL:
