Abstract

A novel triangular [Mn3] cluster-based 3D ferrimagnet [Na2Mn3(SO4)3(μ3-OH)2(μ2-OH2)2]n (1) was structurally and magnetically characterized. It exhibited both long-range magnetic ordering (TC = 12.0 K) and spin glass behaviour around 10 K and a butterfly-shaped magnetic hysteresis loop was observed. A peak (14.4 J kg−1 K−1) in the −ΔSmvs. temperature curve was obtained at 13.5 K. It is rather rare that the magnetocaloric effect of a ferrimagnet was explored and that the peak in the −ΔSmvs. temperature curve occurs above 10 K.
