Magnetic Ordering in a Kagome-like Cobalt Sulphate

DOI

We have recently prepared a new cobalt sulphate, Co3(SO4)3(OH)2[enH2], under solvothermal conditions. The structure of this material consists of edge-sharing CoO6 octahedra that form Co9O38 triangles. These triangles are linked through mu3-(OH) and sulphate tetrahedral to generate an anionic layer. The cations in this layer adopt a Kagome-type array of vertex-linked isosceles triangles of magnetic centres. Magnetic data indicate the presence of frustration and show significant deviations from Curie-Weiss behaviour below ca. 16 K, with long-range antiferromagnetic order occurring below TN = 7 K. We propose to collect powder neutron diffraction data on the deuterated analogue as a function of temperature to characterise the long-range magnetically-ordered structure and to follow its evolution through the anomalies in the reciprocal susceptibility data.
