abstract

  • In this work, we present a detailed AC magnetic susceptibility investigation of the metamagnet {[Mn(OH)(CH 3CO 2) 2]·CH 3CO 2H·H 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.
