摘要：

High-field magnetization measurements have been performed in pulsed magnetic fields. Two sharp steps have been observed in the magnetization processes of a Ni dinuclear oxalato(ox)-bridged compound: [Ni-2(Medpt)(2)(mu-ox)(H2O)(2)] (ClO4)(2)2H(2)O (Medpt = methyl-bis(3-aminopropyl)amine) which is regarded as an S = 1 antiferromagnetic (AF) dimer compound. The magnetization and susceptibility data are analyzed in terms of the S = 1 AF dimer model with uniaxial single-ion-type anisotropy. (C) 1998 Elsevier Science B.V. All rights reserved.
