      abstract     = {The nature of the magnetic ground state of the
                      spin-frustrated molecular magnet {Mo72Fe30} is studied using
                      polarized neutron scattering and specific heat methods. The
                      magnetic scattering cross section up to 2.30 angstrom(-1)
                      has been determined by means of diffuse neutron scattering
                      with xyz polarization analysis at temperatures from 1.5 to
                      100 K. The spin correlations observed at 1.5 K agree well
                      with the simulation based on the three-sublattice spin
                      configuration model for {Mo72Fe30}. The specific heat of
                      {Mo72Fe30} has been measured from 60 mK to 15 K under zero
                      external magnetic field. The energy gaps, 0.09(1) and
                      0.64(1) meV, identified by the Schottky-type anomalies in
                      the specific heat data are in reasonable agreement with the
                      low-lying magnetic excitations predicted by the quantum
                      rotational band model for the three-sublattice spin
                      configuration model. Therefore, our experimental study
                      provides strong support that the three-sublattice spin
                      configuration model is a good approach to the magnetic
                      ground state of {Mo72Fe30}.},
