摘要: An investigation of the magnetic properties cobalt(II) citrate cubane [C(NH2)3]8{Co4(cit)4}·4H2O reveals that cluster is a new single-molecule magnet, with an energy barrier to reorientation magnetization, ΔE/kB = 21 K, and τ0 8 × 10−7 s. The compound displays distinct, frequency-dependent peaks in out-of-phase (χ′′) component ac susceptibility magnetization versus field hysteresis loops are temperature sweep rate dependent. collapse at zero due very fast quantum tunneling (QTM).
