Abstract: We report here the magnetization and Eu-151 Mossbauer studies in ordered perovskite-type oxides, Ba2EuRu1-xCUxO6 (x=0.0, 0.1 and 0.2). The parent compound, Ba2EuRuO6, shows a magnetic ordering at 40 K. Both the magnetization and Mossbauer measurements indicate that the magnetic ordering temperature is unchanged as Cu partially substitutes Ru. Despite the fact that the ground state of Eu3+ is a nonmagnetic J=O state, the Eu-151 Mossbauer resonance spectrum shows a clear splitting into six lines for T < T-N, indicating a large magnetic hyperfine field (similar to 280 kOe). This large hyperfine field may be arising due to a strong exchange field between the ordered Ru moments acting on the Eu3+ ions, inducing a magnetic moment for the Eu3+ ions.
