They adopt the 12L-perovskite-type structure consisting of Ru3O12 trimers and LnO6 octahedra. All of these compounds show an antiferromagnetic transition at 2.5-30 K. For Ba4NdRu3O12, ferrimagnetic ordering has been observed at 11.5 K. The observed magnetic transition is due to the magnetic behavior of the Ru^[4.33+]3O12 trimer with S=1/2. Magnetic properties of Ba4LnRu3O12 were compared with those of triple perovskites Ba3LnRu2O9 and double perovskites Ba2LnRuO6.Elsevier2010-01engjournal articleAMhttp://hdl.handle.net/2115/42628https://doi.org/10.1016/j.jssc.2009.10.0070022-4596Journal of Solid State Chemistry18313340https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/42628/1/JSSC183-1_33-40.pdfapplication/pdf694.09 KB2010-01
