abstract

  • In this work, we present a detailed AC magnetic susceptibility investigation of the metamagnet {[Mn(OH)(CH 3CO 2) 2]CH 3CO 2HH 2O} (1). Compound 1 was previously reported and the magnetic properties were investigated. The data revealed that the compound is a linear-chain antiferromagnet with a phase transition at T N = 6.1 K to an ordered antiferromagnetic state and a metamagnetic transition at approximately 1000 Oe from the antiferromagnetic phase to a paramagnetic phase. In this new study we report detailed AC susceptibility measurements which reveal frequency dependent data indicative of a slow relaxation process which was not previously described. These additional magnetic data support the conclusion that this compound is a rare example of an antiferromagnetic ordered system that displays magnetic relaxation properties induced by the intrinsic single chain magnet (SCM) properties of the canted homospin chains composing the material. 2012 Elsevier B.V.
