Belov K.P. , Valyanskaya T.V. , Mill' B.V., Sokolov V.I., Solov'eva N.A.
Measurements of the heat capacity of garnets containing two types of 3d ions in one (octahedral) or two (octaand dodecahedral) sublattices shows that an antiferromagnetic ordered state of the cluster type is realized in these compounds.
