Description Exchange bias properties are observed in a double perovskite compound, Sr(2)LuRuO(6). The observed exchange bias properties have been analyzed on the basis of some of the available theoretical models. Detailed magnetization measurements show that the exchange bias properties are associated with the Dzyaloshinsky-Moria (D-M) interaction among the antiferromagnetically ordered Ru moments (T(N) similar to 32 K). In addition to the usual canting of the antiferromagnetic moments, D-M interaction in this compound also causes a magnetization reversal at T similar to 26 K, which seems to trigger the exchange bias properties. Heat capacity measurements confirm the two magnetic anomalies.
