Low-lying magnetic excitation of cyclic molecular magnet {Cr8Y8}
A hexadenuclear heterometallic wheel-like molecular cluster {Cr8Y8} was synthesized. The magnetic susceptibility shows that the magnetic interaction is ferromagnetic between CrIII ions. {Cr8Y8} provides a rare example of ferromagnetic rings. Specific heat data show distinct Schottky anomalies, indicating the presence of low-lying magnetic excitations. The energy gaps resolved from specific heat data and INS data are partially consistent with each other, and can be approximated by a single-J model. Specific heat data also shows a small energy gap about 9.3 micro eV, which may be due to the zero-field splitting of the S=12 ground state. This energy gap could not be measured in our previous INS measurements due to the limitation of instrumental resolution. We propose to use high resolution backscattering spectrometer IN16B to determine precisely this low-lying zero-field splitting in {Cr8Y8}.
