Description Magnetic, 151Eu Mössbauer and specific heat measurements have been carried out on image compounds. From the magnetization data, all the compounds are found to be antiferromagnetically ordered near 40 K, independent of Cu content. A sharp peak at 40 K in the specific heat data also confirms the magnetic ordering. The Eu ions in all the compounds are in the 3+ state as inferred from the 151Eu Mössbauer isomer shift values. However, a well split, six line pattern is observed in the 151Eu Mössbauer spectra of these compounds below 40 K. This is rather rare for image which is a nonmagnetic ion. The magnetic hyperfine field at the Eu site is found to be image at 4.2 K and is presumed to arise due to the strong Ru–O–Eu exchange interaction.
