Tuning the magnetic properties of the high-spin molecular cluster Fe(8)

Tunneling of the magnetic moment is just one quantum phenomenon observable in molecular clusters of magnetic transition metal ions. Such tunneling through the energy barrier, generated by the magnetic anisotropy, is shown schematically. The role of the transverse anisotropy in the low-temperature. dynamics of the magnetization can be elucidated through the comparison of the tunneling rate of the magnetization. of two Fes cluster compounds, differing only in the transverse anisotropy.
