Description Here we report the magnetic and heat capacity studies of the double perovskite compounds Ba(2)SmRuO(6) and Ba(2)DyRuO(6). Anti ferromagnetic transitions are inferred at 54 and 47 K in Ba(2)SmRuO(6) and Ba(2)DyRuO(6), respectively, in the magnetization measurements. Heat capacity measurements show large jumps at the corresponding temperatures and confirm the bulk magnetic ordering. Both the measurements provide clear indication of the ordering of the rare earth moments also along with the Ruthenium moments. However, the heat capacity results suggest that the ordering of rare earth magnetic moments is spread over a large temperature range. An anomaly observed in the magnetization measurements at 42 K (below the magnetic ordering) in Ba(2)SmRuO(6) is discerned as a reorientation of Sm(3+) moments. (C) 2009
