本文研究了纯Mn_（12）-Ac和Cr/Fe掺杂Mn_（12）-Ac的单分子磁体。用交流磁化率技术鉴定了混晶的成分。计算了Mn_（12-Ac）的基态自旋和各向异性参数：Mn_（11）Cr-Ac（S = 19/2，D = 0.62K，B = 0.0009 K，Δ = 63 K）和Mn_（11）Fe-Ac（S = 21/2，D = 0.39K，B = 0.001 K，Δ = 55 K）。讨论了磁各向异性的单离子起源。
This paper investigates the single-molecule magnets of pure and Cr/Fe-doped Mn12-Ac. The components of the mixed crystals are identified by AC susceptibility technique. The ground-state spin and anisotropy parameters of doped Mn12-Ac are obtained: (i) Mn11Cr-Ac (S = 19/2, D = 0.62K, B = 0.0009 K, Δ = 63K), and (ii) Mn11Fe-Ac (S = 21/2, D = 0.39K, B = 0.001 K, Δ = 55K). The single-ion origin of the magnetic anisotropy is discussed.
